清朝,乾隆年間に武英殿が刊行した『医宗金鑑』は最後の漢方医学全書といわれた書である。清朝の盛時に大学士鄂爾泰らが高宗の勅命を受け,国家的規模で編成した近世中国医学の代表的医書である。総計90巻のこの医学書を実際に纏め上げたのは医官の呉謙らで,医家の実用を主旨として編集され,最初に『傷寒論』『金匱要略』という基本書をおき,後に図,説,歌訣でわかりやすく解説している。 その明解さは『四庫全書提要』において評価され,「学者をして考究し易く,誦習に便ならしめてある」と書かれている。こうした実用書が望まれた背景には,「聖済総録や和剤局方などの官選医書もただ博いだけで要は少なく,或は偏して中を失い実際の治療に裨益するものではない」ということがあったためで,日常の臨床の際に役立てることを考えれば,単に網羅してある医書では扱いに手間取るため,わかりやすく覚えやすい医学書が望まれていたのであろう。

The internal shell structure of Bentharca asperula (DALL) is examined under a scanning electron microscope. Living specimens were collected at the sea bottom off Hachijo Island, Tokyo (33°03.5'N ; 140°45.3'E). The shell mainly is composed of outer and inner calcareous shell layers. The former shell layer is made of crossed lamellar structure and the latter is of complex crossed lamellar structure. The crossed lamellar structure of this species is same to the typical crossed lamellar structure of the other Arcoids. Next, there are several different types of the aggregation of crystallites in the complex crossed lamellar structure. The complex crossed lamellar structure of this species is characterized by the parallel arrangement of elongate rod-like crystallites which is inclined toward the ventral margin. Tubules penetrate outer and inner calcareous layers. The openings distribute at the region of inner shell layer on an inner shell surface. The mineral kind of crystallites of both layers is aragonitic crystal. The form of crystallites is elongate rod. The internal shell structure of Bentharca asperula, one of deep sea molluscs, is not special, but is common to one of the other species of Arcoids.

Follow-up case by telephone was conducted for the discharged patients, who had received the medication consulting services from clinical pharmacists of Kobe university hospital. In this trial, we focused on the patients in the Department of Circulation and Respiratory Diseases. The follow-up case by telephone was carried out from the time of discharge until the next visit (almost 2 weeks after discharge). The patients consisted of 30 men and 17 women (average age was 66.9 years old). By telephone, the following issues were questioned; 1 : medication compliance, 2 : side effects and/or the changes of physical condition, 3 : other issues (such a when an inappropriate use of medicine had been suspected during hospitalization). When the patients so desire they could come in for a check-up anytime. More than about 90% of patients reported to keep good medication compliance and to have no significant side effects. However, 34% of patients claimed a slight of change in their physical condition including dropsical swelling, boiling and gasping. The claims were found more frequency in patients who had been suspected of inappropriately taking their medication. Follow-up care by telephone was found to be an effective way to avoid any kind of risks including the discontinuation of medicine. As a result, although further examinations should be addressed, follow-up care by telephone appears to be a good way to ensure the appropriate use of medicine.

While comparing the ways of naming places in Japan, I have brought together data revealed in existing materials and by on the spot investigations made while in Java during the war. Place names in Java originally derive chiefly from the Djawa, Sunda, and Madura tongues of the Malay language groups, and the influence of the Hindu culture which was dominant until about the fifteenth century is quite pronounced. Over against this, Islam, the dominating religion of the present exercises but small influence. And the few place names from the Dutch were crased following independence.First, in connection with the roots of the name “Djawa” I have introduced the opinion set farth by Prof. Purbatjaraka in his “Rice” and the theory resting upon the common expression “pulo dawa” (long island). In what follows I shall explain the numerous and not so numerous origins of Javanese place names. Outstanding are the extreely large number of instances where village names come from coupling the names of plants and animals, particularly with river (kali, tji), spring (sumber) and pool (kedung).Severally it may be said that names are taken plain and simply directly from the surrounding natural scene and that many of them are directly linked with a naïvelife, very concrete, obvious, and without design. The Javanese tend to link auspicious names for historic places and principal towns (e.g. Djakarta=City of Success) and this manner of name-giving was favored even for the big plantations developed after the arrival of the Dutch. Their form and volcanic activity are reflected just as they are in the names of mountains. By connecting even bazzar (pasar) which are the heart of the farming village's economy to specific market days place names are formed. A want of interest in the sea is shown by the lack of place names alleeding to coves, harbars, ports and beaches. It is thus also with fisheries. The lack of place names having to do with communications and the military as well as with the names of crops including rice, beasts of burden, and particularly with paddies, fields and plains is altogether unexpected. Place names whose origins have to do with religions belief are to be seen occasionally (e.g. Priangan=Per-hijang-an Place of Gods) but rather than sacred terms of the Hindu era or even Islamic institutions giving names to villages, cases where villages lend their names to them are numerous. And there are no names associating religious edifices with villages. Even names connected with minig and the nature of the land practically nonexistant.

Onco-TainTM Vial, which was developed to prevent occupational exposures to hazardous drugs such as antineoplastic drugs, is a vial preparation equipped with sheathings (a PVC reinforced base and a shrink wrapping of a protective PET sleeve on the vial). The shatter-resistance of the Onco-Tain™ vial was evaluated with a free fall test. Four types (9 strengths in total) of Onco-Tain™ vials, which contain antineoplastic agents and are available worldwide, were used in the test. Vials with the PVC bases and PET sleeves removed from the Onco-Tain™ vial were used as the control. Mimicking the fall of vials in the medical setting, the falling heights were set at 70, 135 and 180 cm, and the breakage ratios of vials and the scattering area of contents were measured.In the control group (Non-OT group), 3.5, 9.4 and 8.9 percent of vials were broken at the heights of 70, 135 and 180 cm, respectively, and the scattering of contents was observed in all broken vials. The breakage ratios of vials in the Onco-Tain™ vial group (OT group) were statistically significantly lower (0.0 and 2.4%) at the heights of 70 and 135 cm, and tended to be lower (3.3%) at the height of 180 cm. No leakage was observed in vials broken in the OT group. The significant improvement of shatter-resistance of vials was confirmed by applying the protection sleeves to the surface of the vials. By applying these concepts in the future, a decrease of occupational exposures to hazardous drugs caused by the breakage of containers is expected.

Pravastatin sodium tablets are widely used for the treatment of hyperlipidemia,and 22 generic products of this compound have been approved in Japan.A few studies have compared the clinical efficacy of the original and generic forms,and 1 study has questioned the reliability of biological equivalency tests.We therefore retrospectively examined the effect of substituting a generic product (Mevan TM ; Nichi-iko Pharmaceutical Co.,Ltd.) for the original product (Mevalotin TM ; Daiichi Sankyo Co.,Ltd.) on clinical efficacy and safety.We targeted patients who were initially treated with the original product and then the generic product,and from electronic medical records,obtained their prescription data for 3 months before and after generic substitution.Next,we investigated clinical equivalence with regard to changes in total cholesterol (TC),HDL cholesterol (HDL),LDL cholesterol (LDL),and triglyceride (TG) levels as indices of clinical efficacy,as well as in ALT,AST,γ-GTP,and CPK levels as indices of safety.We examined the changes in each of these laboratory parameters between 3 months before substitution and 3 months after substitution.In 293 patients,no significant differences were observed in the indices of efficacy between before and after substitution.We also examined records for presence of diabetes mellitus and familial hypercholesterolemia and their influence on TC levels before and after substitution but no significant differences were observed in this regard.Accordingly,we concluded that the generic product investigated in this study was clinically as effective as the original product.

Sulbactam sodium-ampicillin sodium (hereinafter referred to as SBT/ABPC) injections are widely used for the treatment of infection and in view of this,we conducted a study to examine the therapeutic equivalence of original and generic preparations of SBT/ABPC.In it,we compared efficacy and safety in patients diagnosed with pneumonia,acute bronchitis,or acute bronchiolitis who received the original or a generic SBT/ABPC injection at the National Organization Kanazawa Medical Center from May 2007 to March 2008.We analyzed the efficacy endpoints of body temperature,white blood cell count,and CRP level and the safety endpoints of AST (GOT),ALT (GPT),and BUN in 121 subjects receiving the original preparation and 112 receiving the generic one.Our results suggest therapeutic equivalence for both efficacy and safety,and we conclude that the generic version can definitely be used as an alternative to the original preparation.

A comparative study was carried out to evaluate the quality of one brand name tablet (A) and five generic tablets (B∼F) containing 5 mg of enalapril maleate (ENA). Tablet quality was evaluated based on such characteristics as content, impurities, dissolution profile, hygroscopic properties, and stability. In the purity test, we measured the quantities of degradation products such as diacid compound (DA) and diketopiperazine compound (DKP) and in the hygroscopicity test, the weight and hardness of the tablets without blister packaging was measured initially and after 2 weeks and 4 weeks of storage at 0%, 43%, 75% and 93% relative humidity (RH). To test stability, we measured the quantities of ENA, DA, and DKP in tablets stored without blister packaging at 40°C and 75% RH for 12 weeks.The ENA content in all preparations was approximately equal to the indicated content. Initially, DA was not detected in any of the preparations. About 0.3% DKP was detected in preparation B and C. The dissolution profiles of all generic tablets were similar to those of the brand name tablet. For preparations A, B, and D, a marked increase in tablet weight and decrease in tablet hardness was observed with increasing RH. In the stability test, the remaining ENA content in preparations A, B, and D after 12 weeks was significantly lower than the initial content. The DA content in preparations A and D had increased markedly after 12 weeks and so had the DKP content in preparation B.Our study showed that the quality of the generic tablets C, E, and F was comparable to that of brand name tablet A with respect to stability and resistance to humidity. We conclude that if generic manufacturers continue to produce such high quality drugs, this will lead to greater confidence in their effectiveness and an increase in their use in the clinical setting.

This paper describes an application of a neural network for estimating the ground rainfall from radar echo data. A neural network system for this purpose is developed through a case study on a dam for hydro-power plant located the upper district of the Ooi River in Central Japan. We use the neural network comprised of three layers; an input layer, a hidden layer and output layer. The input data to the neural network are any numebr of radar echo amount observed in each radar mesh and x-y-z coordinates showing its location.<br> The four types of neural networks with different number of input units are proposed and discussed the relative importance of the number of input data. It is found that the estimating system using the most simple neural network yields good results for rainfall distribution.

According to the modified method of Brdieka and Mu ller, Polarographic serum reactions were carried out on 109 patients with urogenital diseases, which were divided into. the following six groups : Group A—malignant tumors, Group B—benign tumors, Group C—tuberculous diseases, Grcup D—urolithiasis, Group E—inflammation and other pathological condition in urogenital organs, Control Group—normal individuals. The protein waves were determined and their clinical usefulness for diagnosis of cancer was examined. Method A.: Direct Test (Total protein Reaction) i) The First Method To 0.05 cc. n a tive serum was added 10 cc. ammoniacal cobaltous solution (A, solution) and the mixture was polarographed. ii) The Second Meth od To 0.3 cc. seru m were added 0.3 cc. distilled water and 0.15 cc. of IM.KOH, the mixture shaken, and after standing for 20 minutes at room temperature, to 0.1 cc. of the mixture 20 cc. of A solution was added and polarographed. B Filtrate Test (Filtrate Reaction) iii) Third Method To 0.5 cc. serum were added 1.0 cc. distilled water, and 1.0 cc. of 20Yo sulfosalicylic acid solution (S.S.A.), the mixture thoroughly shaken and left standing at room temperature. Exactly after 10 minutes the mixture was filtered through a 5.5 cm. NO.5 Toyo filter-paper. To 0.5 cc. of the filtrate was added 5.0cc. ammoniacal cobaltous solution (B solution) and polarographed. iv) The Fourth Method To 0.5 cc. seru m 1.0 cc. distilled water and 0.1 cc. of 1M. KOH were added, the mixture shaken and allowed to stand for 30 minutes at room temperature. Then 1.0 cc. of 20% S.S.A. solution was added, the contents of the tube shaken, and after standing exactly 10 minutes was filtered. To 0.5cc. of the filtrate was added 5.0 cc. B solution and polarographed. v) The Fifth Method This is a way according to Sato's method. To 0.1 cc. serum was added 5.0 cc. of 60% methanol solution, the mixture shaken in a tube with tightly fitting stopper, left standing at room temperature for 30 minutes and then filtered.

Consequently, the diagnostic usefulness of this method for carcinoma seems to be very little and there is almost no significant difference among these groups. Both of the values of wave height rate (W2/W1 and W1/W2) in each group were distributed within a normal range and no significant difference was found. Finally, it seems difficult to find any clinical significance by means of the first method alone. 2.

Clinical application of the second method seems to be more useful than the first method, although this reaction is not specific for carcinoma. Malignant tumors showed 83% of positive result, and nearly the same percentage was seen in urolithiasis and pyonephrosis, but other urogenital diseases generally showed lower positive percentages than malignant tumors. Percentages of positive rasults, however, were somewhat different among the urogenital organs even in cancer. In wave height rate only one case of e ssential renal hamaturia showed a value of 1.1 in W2/W1 which was remarkably lower than that of the control group and 1.0 in W1/W2w hich was higher. The values in all the other diseases were distributed withi n the normal range and neither significant difference between those diseases and control group nor clinical significance of this test was recognized.

A 55-year-old male visited our department for further examination with positive fecal occul blood test results in the mass screening for colorectal cancer. He complained of abdominal pain and diarrhea which had started about 2 months before. Small ulcers and erosions were observed in the ascending colon and cecum at colonoscopy. Biopsied specimen at the erosions showed numerous trophozoites in the mucosa. Many Lamblias were observed under a microscope in residual liquid collected in the ascending colon or cecum. Thus, this patient was diagnosed as amoebic colitis complicated with Giardiasis. At colonoscopy performed 3 weeks after Metronidazole therapy (1000mg/day) , erosions and ulcers in the ascending colon and cecum disappeared. This patient was thought to be infected with both parasites by taking contaminated foods because he was not homosexual and had no HIV antibody.

リコンフィギュラブル・コンピューティングとは、FPGA等の再構成可能ロジックを用いて、アルゴリズム全体または一部を論理回路として実装する方法である。これにより、既存のアルゴリズム実現方法であるASICとソフトウェアの中間に位置して、両者の長所である高速性と柔軟性の両立を目的とする。本稿では、リコンフィグラブル・コンピューティングの1システム実現手法である「再構成可能コプロセッサ」に注目し、その性能評価環境について議論する。そして、MPEG2デコード処理への再構成可能コプロセッサの適用例、ならびに、当該性能評価環境上での実装法について紹介する。Reconfigurable computing (RC) is a methodology to implement algorithms by means of reconfigurable fabric such as FPGA, and it aims at exploiting both benefits of two existing methodologies, or high performance of custom hardware approach and high flexibility of processor-based software approach. The paper discusses one of the approaches to RC, or reconfigurable coprocessing, and then describes the development of a testbed system for reconfigurable coprocessing systems. The paper also tries to apply the reconfigurable coprocessing to MPEG2 decoding process, and discusses how to implement it on the testbed system.

本研究は,若年層を中心に拡大するソーシャルネットワーキングサービスに着目し,その使い方に「世間」に対する考え方が現れるのかを検討したものである。結果として,SNS 利用そのものではなく,SNS を利用する環境,つまりモバイルメディアの利用そのものに,「世間」の考え方が表出することがわかった。世間とは非常に主観的概念であるが,世間内からの人の評価という意味での視線を気にする一方,見ず知らずの人からの視線は想像が出来ない学生も多く存在し,そのような対人関係やコミュニケーションの有り方が,モバイルメディアの利用行動を決定付けていると考えられる。特に,社会的マナーをおろそかに考えがち,見ず知らずの人に親切にする必要はない,ニュースは自分には関係ないといった考え方をする人ほど,身近な人に親切にするといった意味の世間を重要視し,世間に縛られていることがわかった。

In spite of strict laws prohibiting it, criminal cases involving marijuana abuse are increasing, resulting in a serious social problem in Japan. The most common method of ingestion is smoking, since abusers feel that this method produces quick psychological effects controversial. Marijuana is known to induce psychological addiction, but it's genotoxic effects are still argued. Marijuana smoking tar has been extracted from seized pipes. The amounts of polycyclic aromatic hydrocarbons (PAH) in the tar were weighed and the mutagenic activity was tested.The results are as follows:1) Five of the seven PAHs were detected in marijuana tar, although benzo (e) pyrene and perylene were not.2) There was more pyrene than any other substance detected in the tar, with fluoranthene having the next highest concentration.3) Mutagenic activity was observed in all samples, with relative mutagenic potency ranging from 0.03 to 1.59.4) The type of smoking pipe and burning temperature may affect the mutagenic activity and the amount of PAH.5) Since marijuana smoking tar contains carcinogens, promoters, and mutagens, there is a risk of developing cancer just as in the case of tobacco.
