n-Hexane and benezene are organic compounds which have been widely used as industrial solvents. However, they are also increasingly recognized as important pollutants in working environment. The purpose of this study is to analyze neurotoxicity of benzene and n-Hexane. In this study, tibial nerve of Sprague-Dawley rats were observed after exposing them to two different concentrations of these compounds (6000 ppm of n-Hexane and 2000 ppm of benezene) which were known to be the levels to cause subacute toxicity for the three different periods; two weeks, four weeks, and sex weeks. The following results were obtained from the analysis of variance, Duncan's multiple comparison test, and regression analysis: 1) Myelin sheath thickness of nerve fiber for two n-Hexane exposed groups (four weeks and six weeks) were both reduced compared with the control group and the benezene exposed group. 2) There were positive relationships between nerve fiber diameter and myelin sheath thickness for both exposed and control groups. 3) There were significant difference in myelin sheath thickness from equal diameter nerve fibers between benzene exposed group and control group, but the greater number of thin myelin sheath were observed for n-Hexane exposed group compared with control group. Thus, it is concluded that n-Hexane tends to reduce the rate of growth of nerve fiber more than the benzene and control group. While these results shed light on understanding the effects of benzene and n-Hexane, the duration of exposure was not long enough to apply these results to real working environments. In addition, to further understand the mechanism of nerve degeneration caused by organic solvents, both epidemiological and biochemical studies should accompanied by this kind of study.

63 of 348 patients patch tested with an European standard series, had positive reaction to either a fragrance mix or Balsam of Peru. Twelve showed positiv reaction to bot,h patches. The number of positive patch tests to the fragrance mix was 56, while those to Balsarn of Peru was 19 out, of the 63 patients, manifesting sensitivities of 83% and 30% repectively. The fragrance mix was considered a useful screening patch for fragrance allergies. Twenty-five of the patients showing fragrance allergy were further analysed with 8 individual fragrance ingredients at 2% petrolatum. Cinnamic aldehyde and cinnamic alcohol were considered as she most frequent and important. sensitizers.

Though many effort,s have been made to develop a safe and effective treatment to control osmidrosis, no such goal has been achieved yet. A subcutaneous shaving method, developed by Inaba, appeared to be a favorable choice because of minimal postoperative scar formation. The authors, with this method operated on 112 cases of osmidrosis and compared the results with those of conventianal surgical therapy performed earlier in our department. The results were as follows : 1. The. average age at the time of the operation was 22.0 years old, and the sex ratio between male and female was 37 to 75. 2. The age onset ranged from 11 to 36 years with average of 15.5 years. 3. Family history for osmidrosis was found in 84.8%. 4. General anesthesia were used in 13 cases, while 99 cases were operated under local anesthesia. 5. The mean duration for operation were 75 minutes. 6. Flematoma were observed in 4.5%, wound disruption in 1.3%, and skin necrosis in 3.1%. 7. The results of analysis in 72 follow up cases for more than 6 months showed: 1). Rate for successful reduction of the malodor was 91.7%. 2) The rate of suppression of sweating was 88.9%. 3) The rate of skin tensian with motion was 2.8%. 4 ) The, pstoperative scars were mild or invisible in 95.1%

Newborns with ileal atresia frequently present with abdominal distension, bilious vomiting, and failure to pass meconium. Diagnosis is usually established on plain x-ray of the abdomen by the findings of distended small bowel loops and air-fluid levels. In the period of October 1988 to February 1994, 8 patients with congenital ileal atresia were operated and the following results were obtained. 1. Eight patients were comprise of 4 males and 4 females, the ratio of male and female was 1 : 1. 2. Six patients(75%) had been admitted to our hospital during three days of life. 3. Congenital ileal atresia was in 8 cases : Type I in two(25%), Type II in two(25%), Type III a in three(37.5%), Type III b in one(12.5%). 4. There was one premature patient who was small for gestational age. 5. Overall, abdominal distension and bilious vomiting occurring in seven patients, were frequent presenting complaints. 6. Diagnosis was possible with clinical symptom and simple abdomen. 7. Operative treatment was undertaken as soon as the diagnosis was made. In seven cases a primary end-to-end anastomosis was performed after resection of dilated proximal loop. 8. A total of four associated congenital anomalies were found in one patient. 9. Postoperative complications occurred in three cases(37.5%).

Recently cryogenic therapy is widely used for the treatment of herpes simplex keratitis. We had experimental studies on the effect of iodine cautery and cryocautery upon the regeneration of corneal ulceration. On 10 adult albino rabbits, one eye was treated by iodine, and the other by cryocautery in area of 0.6cm X 0.6cm. The epithelium in this area was completly removed by cotton applicator. There after, the rate of epithelial regeneration was observed every 12 hours. The results were as follows: (1) The average period of complete epithelial regeneration was 48 hours in animal treated with cryocautery and 78 hours in animals treated with iodine cautery. This difference is statistically highly significant. (2) Corneal opacity was not demonstrated in eyes treated with cryocautery. Six eyes treated with iodine, however, showed various degree of corneal opacities. These results support the view that the healing time in human herpes simplex keratitis is shortened in patients with cryocautery as compared with iodine.

Infantile hypertrophic pyloric stenosis(IHPS), which occurs three of 1,000 live births, is a major cause of 1 nonbilious vomiting of early infancy but its etiology and pathogenesis are still obscure. The operation of pyloromyotomy as described by Ramstedt in 1912 remains the standard of care for the treatment of IHPS. From January 1993 to October 1996, 35 infants with IHPS were surgically treated and the following results were obtained. 1. Thirty-five patients comprised 32 males and 3 females, and the ratio of male to female was 10.7:1. 2. The most prevalent age group was between 2 weeks and 8 weeks. 3. Of 35 infants, first born babies were 23 cases(65.7%). 4. Breast feeding was in 23 cases(65.7%). 5. The body weight percentile at admission was lower than 50 percentile in all 35 cases. 11. A total of seven associated anomalies were noted in six patients. 12. All 35 cases were treated with Fredet-Ramstedt pyloromyotomy. 13. There were postoperative complications of wound infection in 2 cases. Intermittent nonprojectile vomiting was presented in 8 cases(22.9%) after operation, but one of them was relieved in 13 days and the rest were relieved within one week by adjustment of oral intake.

The syndrome of lower-back pain associated with sciatic pain has probably been a problem since man first assumed the upright position. In 1937 Barr delineated herniation of the nucleu pulposus as a pathologic entity. Since that time, the standard surgical treatment has become laminectomy or laminectomy combined with fusion, with the emphasis on the disc between L4−5 and L5−Sl. Another mode of treatment was suggested when Smith and Brown” reported their clinical experience using intradiskal injection of chymopapain as the definite treatment of lumbar disk disease in 1967. In recent many years investigators in separate clinical studies showed that a benificial result can be achieved in a high percentage of patients treated by chymopapain injection. Our 29 patients who can be observed for more than 6 months after chemonucleolysis were clinically analysed. The results were as follows: 1. Of the 29 patients studied, 15 were males and 14 were females. 11 patients (37.9%) were in age between 41 and 50 years. 2. On clinical symptoms, 24 patients (82.8%) had radicular pain in the lower extremity. All patients had the limitation of the straight leg raising. 3. The most common level of herniated area was L4−5 disk as 22(75.9%) cases. In four cases (13.8 %) two levels of disks (L4−5 and L5−Sl) were involved. 4. On myelography the hour glass appearance was shown in 14 patients (49.3%).Complete block was found in 4 (13.8%) cases. 5. The increase of the straight leg raising was found within 3 weeks after chemonucleolysis in all cases. Motor power were recovered in 20 out of 22 cases and abnormal sensation were recovered in 17 out of 19 cases within 3 months after chemonucleolysis. 6. There were no correlation between persisting low back pain and narrowing of the disk space after chemonucleolysis, statistically. 7. In 23 out of 29 cases discometry test was positive. Among 23 cases, 21 cases recovered from their symptoms successfully after chemonucleolysis. 8. In chymo. R.A.S.T., 9 out of 15 cases were positive in 3 weeks after chemonucleolysis, and 12 out of 15 cases were positive in 3 months after chemonucleolysis.
