The exposures to carbamate pesticides (BPMC specifically) of agricultural workers were estimated by collecting pesticide in air by personal sampler and by analyzing with gas chromatography. Data revealed that the highest BPMC concentration in the aspirated air was 7.7 mg/m3. Concentrations were generally higher in the group whose spray conditions were controlled than the group uncontrolled. Actual concentrations were relatively lower than the values predicted theoretically. These findings suggest that personal sampler be useful in the estimation of pesticide exposure.

Endoscopic sphincterotomy(EST) is now an established therapeutic procedure for various disorder of the pailla of Vater, the biliary tract, and the pancreas. From November 1992 to September l993, 123 cases of E.S.T were performed in our hospital. The success rate of EST was 97.8%, and choledocholithiasis was the indication for EST in 63. 4% of cases. Among 78 cases of choledocholithiasis, 47 cases were presence of gall bladder with stone (16 cases) or without stone (31 cases), especially 46 cases were assisted with needle type papillotome and 23 cases were assisted with guidewire. EST hae relatively low complications and is the therapy of choice for choledocholithiasis and various diisease of biliary tract. Guidewire assisted stanard papillotome probable reduce the use of needle type papillotome in the difficult cases that EST with pull type papillotome was impossible.

The lymphangioma is a benign vascular tumor and, like hemangioma, represents a hamartomatous growths. The site of predilection include the head, neck. and axillae. Lymphangiomas tend to involve the bulbar conjunctiva as well as the eyelid and orbit. Histopathologieally three types of lymphangioma are encountered: demal, cavernous and cystit types. The clinical signs are proptosis, diffuse hematoma of eyelid and subconjunctival hemorrhage. Asymptomatic cases can be observed. The authors experienced a case of multiple lymphangiomas on the right supraorbital area in a 14-year-old man and reported light microscopic and electron microscopic findings of the lymphangioma.

Kerion celsi is severe inflammatory type of tinea capitis. It occurs almost exclusively in pre-pubertal children. We report a case of Kerion celsi occuring in a 79-year-old woman. Culture of infected hair on Sabouraud glucose agar showed Microsporum canis Farnily history and fungus study suggested the importance of indirect route in Microsporum canis infection.

Treatment by External Fixation with External Compression Device was used for the displaced fractures of the proximal humerus. Especially in the old aged patient and patient with severe associated injury, this method was excellent for the early, painless motion of the shoulder and then good functional result. This experimental treatment was performed in 8 patients, and its merits were as follows: 1. The technique of operation was relatively easy, and was possible within a short time with minor injury. 2. The quality of reduction was good in all cases. 3. By the compression effect on the fracture site and firm maintenance of reduction during the treatment, solid healing as in internal fixation was possible. 4. Firm maintenance of reduction & minimal injury of soft tissue made possible early painless and wide ROM exercise, and then good functional result.

BP201, porcine lung tissue-derived phospholipids, consists of phosphatidylcholine as a major phospholipid species. BP201 promoted hair growth after application onto the shaved backs of BALB/c and C3H mice. Its effect was enhanced when applied together with minoxidil (MNX) in C3H mice. When the tissue specimens prepared from the shaved skins of BP201-treated and control mice were microscopically examined, the total numbers of hair follicles in both anagen and telogen phases of BP201-treated mice were significantly higher than those of control mice. The numbers of hair follicles in the anagen phase of BP201-treated mice were also higher than those of control mice. In combination with MNX, BP201 further increased the total number of hair follicles, but did not alter the percentage of hair follicles in the anagenic phase. BP201 also increased the proliferation of human hair follicle dermal papilla cells. Collectively, BP201 possesses hair growth promoting potential, which would suggest its use singly or in combination for hair growth products.

Spontaneous cerebrospinal fluid (CSF) leak is a recognized cause of spontaneous intracranial hypotension (SIH). Subdural hematoma (SDH) is a serious but rare complication of SIH. An autologous epidural blood patch at the CSF-leak site can effectively relieve SIH. We report a case of bilateral SDH with SIH caused by a CSF leak originating at the C1-2 level. A 55-year-old male complained of orthostatic headache without neurological signs. His symptoms did not respond to conservative treatments including bed rest, hydration and analgesics. Magnetic resonance imaging showed a subdural hematoma in the bilateral fronto-parietal region, and computed tomography (CT) myelography showed a CSF leak originating at the C1-2 level. The patient underwent successful treatment with a CT-guided epidural blood patch at the CSF-leak site after trephination for bilateral SDH.
