The purpose of this study was to find the effects of the dynamic lumbar stabilization exercise on functional recovery of low back pain patients. The subjects were consisted of sixty patients who had nonspecific subacute low back pain. All subjects randomly assigned to dynamic lumbar stabilization exercise group. Williams exercise group and modalities treatment group. The dynamic lumbar stabilization exercise group received modalities treatment with dynamic lumbar stabilization exercise. Williams exercise group received modalities treatment with Williams flexion exercise and modalities treatment group received modalities treatment without exercise. The Oswestry low back pain disability questionnaire was used to measure disability of low back pain. Assessment was carried out before treatment fur obtain baseline measurement of low back pain and reassessment were carried out at after 20 and 40 treatment sessions. The results of this study were as following: 1. The Oswestry low back pain disability questionnaire scores were significantly decreased after 20th and 40th treatment in dynamic lumber stabilization exercise group(p<.05). 2. The Oswestry low back pain disability questionnaire scores were significantly decreased after 20th and 40th treatment in Williams exercise group(p<.05). 3. The Oswestry low back pain disability questionnaire scores were significantly decreased after 20th and 40th treatment in modalities treatment group(<.05). 4. There were no statistical difference between the 3 groups at pre-treatment with Oswestry low back pain disability questionnaire scores(p>.05). 5. There were no statistical difference between the 3 groups after 20th treatment with Oswestry low back pain disability questionnaire scores(p>.05). 6. There were statistical difference between the 3 groups after 40th treatment with Oswestry low back pain disability questionnaire scores(p<.05). 7. The Oswestry low back pain disability questionnaire scores were significantly decreased after 40th treatment in all 3 groups and the decrement were greater in order of dynamic lumbar stabilization exercise group. Williams exercise group and modalities treatment group.

This study reports the analgesic, anti-inflammatory and membrane-stabilizing property of alcoholic extract of Ophiorrhiza nicobarica (ON), a wild herb, used as an anti-infective ethnomedicine of Nicobarese and Shompen tribes of Great Nicobar Island, India. We for the first time investigated the analgesic and antiinflammatory potential of this herb in acute, subacute and chronic model of inflammation in Swiss albino mice and Wistar albino rats, along with sheep RBC-induced sensitivity and membrane stabilization. The acetic acid induced writhing, tail flick and tail immersion tests are used as a model for evaluating analgesic activity; while the carrageenin-induced paw oedema was used as the model for acute inflammation, dextran-induced oedema as sub-acute and cotton-pellateinduced granuloma as chronic inflammatory model. The probable mode by which ON mediate its effect on inflammatory conditions was studied on sheep RBC-induced sensitivity and membrane stabilization. The in vitro results revealed that the ON extract possesses significant (P < 0.05) dose dependent analgesic and antiinflammatory activity at 200 and 300 mg/kg and its fractions at 50 mg/kg, p.o. respectively, compared to the control groups. However, the extract failed to exhibit membrane-stabilizing property as it unable to reduce the level of haemolysis of RBC exposed to hypotonic solution. The acute toxicity studies of ON extract in rats and mice revealed that the extract was nontoxic even up to 3.0 g/kg body weight of the animals, with a high safety profile. We have isolated ursolic acid, ${\beta}$-sitosterol and harmaline respectively, from the bioactive part of the extract. The results indicated that the O. nicobarica is indeed beneficial in primary health care, and suggest that its anti-inflammatory activity may not be related to membrane-stabilization.

Objectives : This study was designed to examine the effects of hyperbaric oxygen therapy on cerebral infarction. Methods : Fifty-five patients with acute or subacute cerebral infarction were classified into two groups, the study group and control group. The study group was treated by hyperbaric oxygen therapy(HBOT) for 2 weeks(5 times/week) and the control group wasn't treated by HBOT. We compared the score of National Institutes of Health Scale(NIHSS scale) between two groups. We subdivided the study group by TOAST classification and onset stage, and compared the results. All of this data was analyzed by statistical method. Results : The study group patients who were treated by hyperbaric oxygen therapy saw more improvement than the control group patients in NIHSS score, and there was significant consideration. Among the study group patients, we saw more improvement during the first week period than in the course of the second week, and there was significant consideration. Conclusion : These results suggest that hyperbaric oxygen therapy(HBOT) could be a useful medical treatment to treat cerebral infarction. Further studies are needed on more cases to make sure that hyperbaric oxygen therapy (HBOT) is surely effective for cerebral infarction.

The present study was conducted to investigate the potential subacute toxicity of CKD-602 by a 5-day repeated intravenous administration in Sprague-Dawley rats. CKD-602 was administered intravenously to male rats at dose levels of 0, 0.08, 0.2, and 0.5 mg/kg for 5 days. Studies included general observation, body weight changes, ophthalmoscopic examination, hematology, se겨m biochemistry, gross findings at necropsy and organ weight measurement. There were no deaths in any treatment group and treatment related clinical sign was depilation in the 0.5 mg/kg groups. The decrease or suppression of body weight was also observed dose-dependently in all treatment groups. Decreased leukocyte in all treatment groups, decreased platelet in the above 0.2 mg/kg groups and increase in the serum levels of total cholesterol in the 0.5 mg/kg group were considered as a treatment related toxic effects. Decreased weight of thymus in all treatment groups anti decreased weight of spleen in the above 0.2 mg/kg group were observed. The intravenous administration of CKD-602 caused depilation and decreased weight and had toxic effect on the leukocyte, platelet, spleen and thymus. In the condition of this study, the target organs were spleen and thymus and the toxic effect level was determined to be 0.2 mg/kg, but no-observed-adverse-effect level (NOAEL) was considered to be lower than 0.08 mg/kg.

n-Hexane and benzene 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 tp 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 benzene) which were known to be the levels to cause subacute toxicity for the three different periods; two weeks, four weeks, and six 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 benzene exposed group. 2) There were positive relationships between nerve fiber diameter and myelin sheath thickness for both exposed and control groups. 3) There was no 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 mechanims of nerve degeneration caused by organic solvents, both epidemiological and biochemical studies should accompanied by this kind of study.

To elucidate morphologic lesion of porcine exudative epidermitis which is occurred sporadically in Korea, Staphylococcus hyicus subsp. hyicus isolated from the naturally affected pigs was inoculated to suckling pigs. The infected piglets were observed grossly and histopathologically. Although affected piglets were taking acute, subacute, or chronic course, some piglets suffered from chronic disease showed poor prognosis and marked growth depression. Affected peglets had erythematous skin on the face, ear, and abdomen and these localized lesions appear as brownish spots of exudative epidermitis and fromed crust in the early stage. But, after this stage, the skin were covered by viscous greasy exudate and formed blackish brown crust and appeared fissures and hypertrophy. Grossly, there has been hemorrhage with the removal of crust-like materials of epidermis and edematous subcutis. The superficial lymph nodes were edematous and swollen or congested and hemorrhagic. Some piglets had swollen ureters, cysts in the renal cortex, or polyarthritis. A few cases had mild edematous swelling of kidney, intestinal catarrh and congestion of brain. Microscopically, skin lesions had detachment of keralinized layer and parakeratosis of epidermis, hydropic degeneration of epidermal cell, and retrogressive degeneration of hair root sheath. Dermis had edema, and infiltration of neutrophils and mononuclear cells. As the disease was proceeded, there was marked perivasculitis with lots of mononuclear inflammatory cells. More chronic lesions formed granuloma-like bodies(nodules) due to more mononuclear, perivascular inflammatory cell infiltration and proliferation of fibroblast. Lots of plasma cells and eosinophils were also present in dermis. Epidermis was hyperplastic by proliferation of basal cells stratum germinativum and epidermal pegs often extended into the dermis. In secondary infection, lots of neutrophils could be seen in epidermis and derms. Kidney had neutrophilic infiltration, necrotic and cystic glomeruli, and dilation of renal tubules and ureters. Purulent arthritis was sometimes observed in joints. Three days old mice administrated Staphylococcus hyicus subsp hyicus subcutaneously before had focal congestion and hemorrhage, necrosis, and subcutaneous edema of the skin. This observation was also seen in the study of mice administrated exfoliatin toxin of Staphylococcus which evoked human staphylococcal scalded skin syndrome.

This study was performed to investigate the preventive effect of KDD against lead toxicity. KDD of 133, 266, 532 and 1,064 mg/kg were administered twice to the rats of Sprague-Dawley strain and then 300 mg/kg lead acetate was given to times, respectively. 1. The $\delta$-ALAD concentration in the urine showed 10.6 ~16.4 mg/kg in the control group indicated statistical significance for the experimental group II, III, IV, V (p<0.05). Also, the Coproporphyrin concentration had 0.119 ~ 0.226 $\mu$g/ml in the control group indicated statiscial significance for the experimental group V of 10 weeks (p<0.05). 2. The $\delta$-ALAD concentration in the blood showed 13.28 ~ 16.08 ALAD unit in the control group indicated statistical significance for the experimental group I (Pb 300 mg/kg) of 6 and 8 weeks, for the experimental group III, IV of 8 and 10 weeks, and for the experimental group V of 4 weeks (p<0.05). The $\delta$-ALAD concentration of experimental group I (Pb 300 mg/kg) group was inclined to decrease during the experiment period. The $\delta$-ALAD concentration of experimental group I (Pb 300 mg/kg) showed statistical significance for the experimental group II, III, IV, V of 6, 8 and 10 weeks. But, there was no statistical significance in the concentration change of hemoglobin, RBC, WBC, hematocrit, Ca, protein among the experimental groups. In conclusion, this study revealed the preventive effect of KDD against lead toxicity and its mechnism inferred to facilitate lead excretion in urinary following hinderance of lead absorption in the gastric-intestine and organs.

Objectives : Transverse myelitis(TM) is characterized by bilateral motor, sensory, and autonomic dysfunction of the spinal cord in the absence of pre-existing neurologic disease. It is an uncommon but not rare condition. But it remains as poorly understood syndrome not only etiologically but also in terms of its clinical behavior. Neurosurgically, It is often quite difficult to distinguish from other surgical intramedullary lesions. We present our clinical experiences of TM in order to assess its clinical behavior and to define the radiological characteristics that can distinguish TM from other intramedullary lesions. Methods : From June 1991 to May 1997, twenty-nine patients with transverse myelitis were admitted to our department. All cases revealed acute or subacute syndrome of non-compressive myelopathy and intramedullary lesions in the MRI. We analyze the radiological data and medical records retrospectively. Results : Patients ranged in age from 16 to 66 years, with 22 males and 7 females. Mean follow-up period was 53 months. For the offending levels, cervical was 5, thoracic 21, and lumbar 3 in number. The patients who presented the return of symptoms after a diminution or abatement of initial symptoms were 7(24%). In the MRI, TM showed typical characteristics of high signal intensity lesions in the center of spinal cord in T2 weighted images and low- to iso-signal intensity in T1 weighted images. A focal nodular enhancement pattern was observed in 58.6%(17/29) of the patients. MR follow-up studies were done in the 21 patients and radiological improvement were verified. Biopsies were done in 3 patients. Normal to good outcome was achieved in 62% of the patients. Conclusion : Transverse myelitis has characteristic radiological findings that can be distinguished from other intramedullary lesions. In our series, it is associated with significant recurrence rates thus, should not be considered a selflimiting disease with good prognosis.
