Zinc (Zn) is an essential nutrient and its deficiency causes growth retardation, immunodeficiency, and neuronal degeneration. Zn homeostasis is tightly controlled by transporting through Zn transporters and by buffering via metallothioneins, all of which are involved in the intricate regulation of Zn concentration and distribution in individual cells. Research in understanding of these molecules has progressed with application of genetic techniques, which allow us to clarify the diverse role of Zn in vivo and in vitro. However, the precise roles and molecular mechanism(s) of Zn's function in allergic response have not been clarified. Mast cells are granulated cells that play a pivotal role in allergic reactions. The granules of mast cells contain various chemical mediators and inflammatory cytokines that are released upon FcεRI crosslinking. In this article, I will describe a role of Zn/Zn transporter in FcεRI-mediated mast cell degranulation and cytokine production. Furthermore, Zn acts as an intracellular signaling molecule, that is, a molecule whose intracellular status is altered in response to an extracellular stimulus in mast cell, and that is capable of transducing the extracellular stimulus into an intracellular signaling event, like Ca2+. I have proposed that there are two classes of Zn signaling: “Early” and “Late” Zn signaling. In this review, I discussed how Zn and its homeostasis affect biological events especially for mast cell-mediated allergy response.

The antagonism of histamine H_2-receptor by SWR-104SA (1'-bromo-N-[3-[3-(1-piperidinylmethyl) phenoxy] propyl]-spiro [1,3-dioxolane-2,9'-pentacyclo-[4. 3. 0. 0.^<2,5>0.^<3,8>0.^<4,7>] nonane]-4'-carboxamide monooxalate) was estimated using the isolated guinea-pig atrium and gastric acid secretion in rats. The concentration-response curves for the positive chronotropic effect of histamine on the atrium were displaced to the right in parallel without change in the maximum response by SWR-104SA and roxatidine acetate hydrochloride (roxatidine). The pA_2 values of SWA-104SA and roxatidine acetate hydrochloride were 7.27 and 7.38,respectively. The slopes of the regression line of log (DR-1) against log SWR-104SA and roxatidine concentration were 1.00 and 0.92,respectively. There was no significant difference between the two compounds with respect to the histamine H_2-receptor antagonism and/or binding manner in vitro. In the rat gastric fistula model stimulated by histamine, however, antisecretory potency of SWR-104SA was 3 times less than that of roxatidine. SWR-104SA given p.o. prevented the formation of gastric lesion induced by HCl-ethanol and indomethacin dose-dependently, roxatidine also prevented its formation by HCl-ethanol, but failed to prevent that by indomethacine. These antiulcer activities of SWR-104SA were shown at the lesser doses of antisecretory activity. On the other hand, roxatidine did not prevent the ulcer formation at the same dose level of antisecretory activity. These results indicate that the antiulcer effect of SWR-104SA is not caused by the antisecretory action alone. In addition, the mucosal protective activity of SWR-104SA for HCl-ethanol induced gastric lesion was independent of endogenous prostaglandins. Moreover SWR-104SA had inhibitory effects on indomethacin-induced gastric hypermotility in rats. These actions may partly explain the gastric protection of this compound and additional mechanisms such as mucosal blood flow could be involved in the antiulcer efficacy. Consequently, it appears that SWR-104SA is a new antiulcer drug that exerts a potent cytoprotective effect in addition to its gastric antisecretory activity.

The survival effect of mice irradiated with a lethal dose of X-ray was studied by use of 60 kinds of Chinese traditional medicines. Methanol extracts of these medicines were prepared, and then each extract injected intraperitoneally into male mice before or after whole-body irradiation. As a result of these studies, the survival effects with Ogi-kentyu-to, Simotu-to, Sessyoin, Zokumei-to and Boi-ogi-to were observed by intraperitoneal injection before irradiation. Of these effective methanol extracts, only Zokumei-to was shown to have a significant survival effect by intraperitoneal injection after irradiation.

Some Glycyrrhiza species grown in several domestic research gardens of medicinal plants were collected by the Osaka University of Pharmaceutical Sciences and were cultivated to compare their morphological properties. HPLC profile analysis was performed and index compounds of MeOH extracts of aerial parts and EtOAc extracts of subterranean parts were determined. Glycyrrhizin contents and growth rates of the underground parts of some types of Glycyrrhiza uralensis and Glycyrrhiza glabra were compared and four excellent types were selected as candidates for cultivation. One of them was due to Kanzo-Yashiki (Enzan, Yamanashi prefecture), where G. uralensis was cultivated in the Edo period. Alkaloidal constituents of G. uralensis and G. glabra were also investigated and anabasine (an insecticide) and a new tricyclic alkaloid were obtained.

Tropacocainhydrochlorid kann eine Stunde lang auf 130° erhitzt werden, ohne dass dabei eine Veranderung (sowohl in chemische als auch in physikalischer Hinsicht) zu befurchten. Erst bei zwei stundigem Erhitzen auf 135-140° wird eine geringe Veranderung wahrnehmbar, die jedoch die Erfordernisse von Ph. Jap. nicht beeintrachigt. Sterilisirt man eine 2% ige wasserige salzsaure Tropacocainlosung nach der ublichen Methode, so bemerkt man ein Zeichen von Verseifung, indem man aus 10 g Salz 0.0004-0.0005 g Benzoesaure und 0.0006-0.0007 g Pseudotropin erhalt. Gegen Hitze ist die wasserige Losung des Pseudotropins sehr bestandig. Erst beim Erhitzen im Einschliessrohr auf 170-180° wird eine Spur Tropidins gebildet.Der Alkaligehalt des weichen Glases wirkt beforded auf die Verseifung der salzsauren Tropacocainlosung. Dem Sonnenlicht bezw. Urtraviolettstrahlen ausgesetzt zeigte das Tropacocainhydrochlorid und seine Losung eine auffallende Bestandigkeit.

Besides the unchanged drug, two major metabolites were found from the urine of animals that received orally high doses of bromazepam, 7-bromo-1,3-dihydro-5-(2-pyridyl)-2H-1,4-benzodiazepin-2-one. The metabolites were purified by column chromatography on silica gel and recrystallization. From the spectral and elemental analysis data, the structure of these metabolites were identified as 2-amino-5-bromobenzoylpyridine and assumed to be 2-amino-5-bromo-3-hydroxybenzoylpyridine, the latter being excreted as its glucuronide in the urine. It may be concluded that bromazepam after opening of the diazepine ring undergoes a process of hydroxylation.

Five metabolites appearing in the urine of the rabbit fed bromazepam were isolated; these are 2-(2-amino-5-bromobenzoyl)pyridine (ABBP), 2-(2-amino-5-bromo-3-hydroxybenzoyl)pyridine (3-OH ABBP), 3-hydroxybromazepam, and two new matabolites, 9-hydroxybromazepam and 5'-hydroxybromazepam. The new metabolites were characterized by thin-layer chromatography (TLC) ; elemental analysis, and infrared, nuclear magnetic resonance, and mass spectrometries. Metabolites, which were excreted mainly as conjugates of glucuronic acid and/or sulfuric acid, were measured by preparative TLC and characteristic colorimetric method after enzymic hydrolysis of the conjugates. Urinary excretion of bromazepam and its metabolites have been studied in dogs, rabbits, mice, rats and guinea pigs after massive doses of bromazepam. The conjugated 3-OH ABBP was the major metabolite in rabbits (17.1% of the dose) and dogs (6.2% of the dose) during 24 hr. The major metabolites found in rats, however, were the conjugated form of 3-OH ABBP (5.3% of the dose), 5'-hydroxybromazepam (4.2% of the dose), and ABBP (3.8% of the dose), and 9-hydroxybromazepam was not excreted. In mice the major metabolite was the unconjugated form of 3-hydroxybromazepam (7.5% of the dose). In guinea pigs, two unknown metabolites, besides the above five metabolites, were excreted, and it was confirmed that one of them was benzhydrol analog of ABBP. When intraperitoneal injection was compared with oral administration of the same dose in the rabbit, the urinary excretion of the ring-cleaved metabolites, ABBP and 3- OH ABBP, decreased, but that of the others, 3-hydroxybromazepam and 5'-hydroxybromazepam, increased. On the basis of these data, pathways of bromazepam were postulated (Chart 1). Quantitative differences in the urinary metabolites of bromazepam in each species was clearly observed during the first 24-hr period.

Mechanoreception and subsequent cellular/molecular mechanisms of signal transduction pathways in response to mechanical stresses, including hemodynamic factors, passive stretching, and exercise, are ubiquitous in living organisms. Of these, the cardiovascular system involving the heart and blood vessels is known to be particularly sensitive to mechanical stimuli, for example, stretching and intraluminal pressurization, which might mimic an acute and/or chronic change in blood pressure and flow, induce a variety of responses including contraction, activation of various kinases and ionic channels, production of vasoactive substances, gene expression, and phenotype changes. We have started to clarify the mechanisms underlying this basic principle in the cardiovascular system as it is now generally considered that obesity and a lack of exercise are serious risk factors for cardiovascular diseases such as hypertension, atherosclerosis, and type 2 diabetes. We further extended our research field of mechanotransduction into adipocytes, skeletal muscle cells, and pancreatic beta cells, all of which are related to the core concerns in cardiovascular disease, including the so-called metabolic syndrome. In the present article, we discuss briefly the prologue to our study of mechanotransduction and several topics in the recent progress in this interesting area. We also emphasize that it is important to recognize biomechanical factors and control them not only for improvement in our knowledge of health and disease but also for the development of new drugs.

Transient receptor potential vanilloid 2 (TRPV2) channels are expressed and play functional roles in various immune cells. Physical stimuli leading to TRPV2 activation causes mast cell degranulation. Besides their roles in immune cells, it has been shown that TRPV2 channels are pathophysiologically relevant to degenerative muscular diseases such as dilated cardiomyopathy and muscular dystrophy. Hence, development of drug candidates that inhibit human TRPV2 activation is an urgent matter. NK-4, a cryptocyanine dye, inhibited agonist-induced TRPV2 activity in mouse TRPV2-transfected HEK293 cells. However, it remains unclear whether NK-4 exerts regulatory effects on the activation of human TRPV2 channels. In this study, we show that NK-4 inhibits intracellular Ca2+ increase in human TRPV2-transfected HEK293 cells preactivated with a TRPV2 agonist. The inhibitory effect of NK-4 (IC50=0.27 μM) on human TRPV2 activation was 74-fold stronger than that on mouse TRPV2 activation (IC50=20 μM). NK-4 also inhibited the agonist-induced TRPV2 expression at the plasma membrane, when the human TRPV2-expressing cells were stimulated with the agonist in the presence of NK-4. These results suggest that NK-4 abrogates the agonist-induced signaling events leading to human TRPV2 activation. Furthermore, TRPV2 agonist caused degranulation of RBL-2H3 cells, which represents a phenomenon related to physical urticarias. NK-4 suppressed the release of β-hexosaminidases upon degradation with IC50 of 1.9 μM, 35-fold lower than that determined with an anti-allergic drug, Epinastine. Our results suggest that NK-4 would be a potential therapeutic strategy to resolve dilated cardiomyopathy and its associated heart failure as well as physical urticarias.

Since it is important that patients take their oral anticancer therapy as prescribed, pharmacists need to assess adherence. In addition, oral anticancer drugs are expensive, and reuse of leftover drugs at outpatient pharmacy clinics is useful in reducing drug costs. The present study aimed to clarify when and why patients have leftover capecitabine tablets, and the cost of leftover capecitabine tablets reused at an outpatient pharmacy clinic, focusing on adjuvant capecitabine plus oxaliplatin (CAPOX) chemotherapy for gastric cancer. We retrospectively studied patients who received adjuvant CAPOX chemotherapy for gastric cancer between November 1, 2015, and April 30, 2021, at the Cancer Institute Hospital of the Japanese Foundation for Cancer Research. The cost of leftover capecitabine reused by pharmacists was calculated based on the National Health Insurance drug price standard for the study period. This study included 64 patients who received adjuvant CAPOX chemotherapy. Thirty-seven patients had 152 leftover capecitabine tablets. The most common reasons for leftover capecitabine tablets were nausea and vomiting (21.7%), missed doses (18.4%), and diarrhea (13.2%). The leftover capecitabine tablets for 25 patients were reused at the outpatient pharmacy clinic at a cost of JPY 604142.8 (JPY 24165.7 per patient). The study results suggest that evaluating capecitabine adherence and the reasons for leftover capecitabine tablets at outpatient pharmacy clinics as well as reusing leftover medication can contribute to reducing drug costs.

Inflammatory bowel disease (IBD) is an autoimmune disease that inflames the intestinal tract and reduces patient quality of life. In recent years, prescriptions of biologics and Janus kinase inhibitors have made outpatient pharmacists indispensable to clinics and hospitals. Therefore, we retrospectively investigated the effectiveness of immunopharmacist outpatient services in treating IBD. The survey spanned between January 2019 and December 2020 and included patients who had visited an IBD-specialized outpatient clinic. The endpoints were the number of pharmaceutical and accepted interventions, improvement rates, and cost-effectiveness of the pharmacist outpatient services. The definition of pharmaceutical intervention involves the pharmacist outpatient clinic, which refers to the number of prescription proposals made to doctors, and the dispensing room, which refers to the number of inquiries made to doctors. The survey included 139 patients, and 579 assessments were performed in the pharmacist outpatient clinic. Out of 352 pharmaceutical interventions by the outpatient pharmacist group, 341 (96.9%) were accepted by physicians. Similarly, out of 74 pharmaceutical interventions by the dispensing group, 54 (73.0%) were accepted by physicians (p<0.0001). The overall improvement rate of pharmaceutical interventions was 93.5%. The immunopharmacist outpatient clinic was found to be cost-effective, with an estimated value of 44068000 yen. In IBD outpatient services, clinical pharmacists and physicians are integral members of the medical care team and have a positive impact on drug treatment outcomes.

The purpose of this narrative review was to clarify the current status and issues of scientific evidence for functionality in the Foods with Function Claims system based on previous research. From the introduction of the system in April 2015 to January 1, 2023, there were 6606 notifications, of which 6297 (95.3) were systematic reviews (SRs) and 309 (4.7%) were clinical trials (CTs). SRs were identified the following problems: i) inadequate description based on the first version of PRISMA checklist, and ii) very low levels of quality assessment in the first version of AMSTAR checklist and AMSTAR 2. CT was reported to have the following problems: i) inconsistencies between the protocol and the content in the paper (non-compliance), ii) high risk of bias, and iii) not described based on the CONSORT 2010 checklist. Since SRs and randomized controlled trials (RCTs) often have low-quality notifications, it is necessary to correctly communicate this information to consumers in order to make appropriate purchasing decisions.
