An epidemiological survey by questionnaire was made on arachnidism caused by the spider, Chiracanthium japonicum, in Japan. Among 42 arachnologists and 79 medical doctors, who are interested in arachnidism, 90 researchers submitted clinical records of bite cases in response to the questionnaire. A total of 28 patients of arachnidism was reported from different prefectures including Hokkaido, Aomori, Fukushima, Iwate, Miyagi, Gumma, Kanagawa, Yamanashi, Aichi, Wakayama, Mie, Nagasaki and Saga. Analysis of these 28 cases was made in which the sex of causative spiders, seasonal frequency, age and sex distribution of patients, location bitten, site of bites, severity and duration of time suffered were examined. From this epidemiological analysis, arachnidism caused by Chiracanthium japonicum was summarized as follows : A) The arachnidism occurred very commonly in Japan during a period of four months from May to August, with a peak in June. B) During the mating season the male spiders searching for mates accidentally infest human hibitats and inflict their bites most commonly during the midnight hour while the humans are sleeping. C) The site of bites was most frequently observed in the upper extremities. D) A drastic difference is observed in arachnidism caused by male versus female spiders. Male spiders produce sharp pain at the bite while the female causes intensive itching. However, both sexes produce redness over the skin lesion.

Arachnidism caused by the genus Chiracanthium has been reported from subtropical or warm temperate zones in all over the world. So far in Japan, total 50 cases of arachnidism caused by C. japonicum, which is recognized to be most dangerous, were recorded and analized epidemiologically from the medical points of view up to 1976. The investigation was made on the function and the histology of the venom apparatus for the purpose of analysing the cause of arachnidism. The venom apparatus is associated with the chelicerae or first pair of appendages of the cephalothorax. Each consists of a large basal segment and a terminal claw-like fang piecerced by the duct from the venom gland. The fang of male is about two times longer than that of female, therefore, the fangs of male was found to be able to penetrate the palmar skin of volunteer more deeper than that of female. The muscularis was found to cover the whole gland beginning from the neck of the gland. This is the bundle of fibers of striated-muscle. The basement membrane from a continuous layer under the muscularis. The two kinds of epithelial cells were observed lining the basement membrane. The first layer is formed by small and low cells with an ovarial nucleus. The second layer is formed by high columnar cells attaching on the basement membrane. Both the nuclei of the first and the second cells show the same morphological structure by the optical microscopy.

Determination of the chemical properties of the venom of Chiracanthium japonicum, which is well known as the most medically important spider in Japan, was studied. The venom was prepared by dissecting out the venom glands from mature female spiders. Then the glands were homogenized in phosphate buffer solution (PBS) with a glass homogenizer. The clear, viscous surpernatant obtained by centrifugation was stored in a small vial and regarded as the crude venom. This venom was fractionated on a Sephadex G-200 column. The white mice (JCL) were injected intraperitoneally with 0.2ml of different concentrations of the fractionated venom. The lethal activity was noted. Lethal activity was fractionated on a CM Sephadex C-50 column. The fractions were regarded as the purified venom. The toxic responses to mice were dyspnea, prostration, flaccid paralysis and death. The lethal activity was determined to be neurotoxic in action. The minimal lethal dose (MLD) of the purified venom for mice was 10μg. The house-fly was used for the toxicity test. The LD_<50> was 0.069μg/honsefly. The erythematic activity on rabbit hide was examined by injecting the venom intradermally. The minimal redness dose (MRD) to evoke 10×10mm size of redness in the rabbit was 0.7μg. The molecular weight of purified protein was 63,000±2,000. The toxicity to mice was completely destroyed by heating at 60℃ in 10 minutes and lost at 0℃ in five to seven days.

1954年から1974年の過去20年間に著者が経験した5種のクモによる10症例の刺咬症を報告した。その他既報例を合わせ9種のクモによる16症例について, クモ刺咬症の発症時期, 発症原因, 被害患者の性, 年代, 病害の程度, 治療の問題点を明らかにした。5月から8月の暖かい季節に発症し, クモを直接手で捕えようとする瞬間に受傷するのが多く, 刺咬部は四肢, とくに上肢に多い。受傷患者は10代に多く, ほとんど男性であった。全症例を病害の程度に従って無症状, 軽症, 中等症, 重症の4つに分類したが, 重症例はセアカゴケグモとカバキコマチグモの2種であった。クモ刺咬部の治療上とくに問題になったのは, 受傷後も持続する耐えがたい痛みに対する治療法で, 一般の視床, 脊髄性鎮痛剤では著効をえられなかったことである。本邦において今迄に報告されたクモ刺咬症についても考察を行った。

A series of surveys have been carried out on the spider species as natural enemies of pest insects in a garden of Sakurababa-machi, Nagasaki city over a period from 1955 to 1959,and from 1963 to 1966. A total of 87 species (61 genera and 26 families) including 40 common species were recorded in the garden through the observation years. The number of spider species was found abundantly from May through August particularly. The predominant species were the spiders belong the families of Argiopidae, Salticidae and Theridiidae. Most of the spiders were distributed in the bush and on the outer walls of the house but few on the ground. The insect species which destroyed by the spiders were also recorded; the preys confirmed were insects belong to the orders of Collenbola, Odonata, Blattaria, Orthoptera, Dermaptera, Isoptera, Hemiptera, Mecoptera, Lepidoptera, Coleoptera, Hymenoptera and Diptera. Especially great numbers of houseflies and chironomids (Diptera) were captured by almost all the spider species in the garden. The chironomids were trapped by the viscid lines of webs.

A study was carried out on the spider fauna of houses in different environments of Nansei Islands, South Japan. In total 24 species belonging to 17 genera and 11 families were collected, among which 11 species were common spiders in houses. No dangerous spider was found in any houses in this survey.
