The authors studied the plasma cholesterol levels in 39 rats (Sprague-Dawley) after 4 weeks administration of etretinate and/or fish oil. The study groups were as follows.'13 rats recieved etretinate only;13, fish oil only;13, both ertetinate and fish oil. Cholesterol levels were determined by standard enzymatic methodology. The results were as follows. Tot,al-cholesterol levels in rats following administration of ertetinate only were increased(p<0.05), but the levels in rats receiving fish oil only and both etretinate and fish oil were markedly decreased(p<0.01). HDL-cholesterol levels in rats following administration of fish oil and both etretinate and fish oil were decreased(p<0.01). The ratio of HDL-cholesterol to total-cholesterol in rats receiving fish oil only and both etretinate and fish oil were increased(p<0.05) because of markedly decreased total-cholesterol levels.

This study was aimed to elucidate the effect of intracerebroventricular losartan administration on arterial pressure regulation during hemorrhage in rats by power spectral analysis of blood pressure and heart rate variability. Nineteen male Sprague-Dawley rats weighing 240-300g were divided into losartan-administered(n=10) and control(n=9) groups. Hemorrhage was induced with a withdrawal pump from the femoral artery at 3ml/kg/min for 5min. Arterial presure was measured with a pressure transducer connected to the contralateral femoral artery for 5min before, during and after hemorrhage. The blood pressure signal digitized at 500 Hz through a data acquisition system was analyzed with fast Fourier transform algorithm to yield power spectra of systolic(SP) and diastolic(DP) blood pressure and instantaneous heart rate(HR). Powers of very low frequency (VLF, 0.02-0.26 Hz), low frequency(LF, 0.26-0.75 Hz) and high frequency(HF, 0.75-5.00 Hz) band were obtained. Basal systolic and diastolic blood pressure was 149+/-9 and 99+/-2mmHg, respectively, and was not changed by hemorrhage in control rats. Basal blood pressure in losartan group was 143+/-9 and 97+/-6mmHg and was significantly lowered to 116+/-13 and 77+/-9mmHg, respectively. HR was significantly increased during and after hemorrhage in both groups. Total power of SP variability in losartan group was 13.9+/-3.2mmHg2 before hemorrhage and was significantly increased to 66.6+/-25.3mmHg2 during hemorrhage. VLF, LF and HF powers of SP variability were 7.3+/-2.0, 3.8+/-1.1 and 2.8+/-0.7mmHg2, respectively, in losartan group and 5.5+/-1.4, 3.7+/-1.5 and 2.8+/-0.8mmHg2 in control rats. VLF and HF powers of SP were increased to 33.0+/-15.2 and 20.3+/-6.4mmHg2 in losartan group, and VLF power was increased to 7.9+/-1.5mmHg2 in control group. VLF power of DP variability increased from 3.3+/-0.9 before hemorrhage to 5.9+/-1.0mmHg2 during hemorrhage in control group. Powers of DP variability in losartan group and those of HR variability in both groups were not changed by hemorrhage. The above results suggested that losartan aggravated the arterial pressure fall during hemorrhage by impairing the sympathetic nerve activation by central angiotensin II.

Open carpal tunnel release surgery has heen the gold standard method of treatment for who did not respond to conservative treatment and whose neurologic symptoms were progressive. However, open carpal tunnel release using a standard incision frequently associated with delayed return of hand function, residual scar tenderness and pillar pain. So, two new alternative methods such as endoscopic carpal tunnel release and limited incision technique have developed. To define the role of the limited two incision technique, we anaiyzed the postoperative functional results of 40 cases in 33 patients. The patients were divided in two groups. Group A was standard incision group (23 cases in 19 patients) and Group B was limited two incision group (l7 cases in 14 patients). The postoperative functional results were analyzed statistically using chi-square test at postoperative 3, 6, 9 and l2 weeks. There were no significant differences in reliet of numbness and paresthesias in both groups. There was a statistically significant difference in relief of scar tenderness and pillar pain at postoperative 3 and 6 weeks in Group B. There was no significant complication in both groups. We can conclude that the limited two incision technique of carpal tunnel release is a safe procedure which allows rapid return of hand functions with reduced incidence of scar tenderness in the early postoperative stages.

Fracture of the femoral neck occurred after internal fixation of intertrochanteric fracture of the femur is very rare and have been described previously in terms of stress fracture, stress-riser fracture, Youngs modulus fracture or iatrogenic fracture in the literature. This fracture documented about 20 cases in the English literature and usually occurred in elderly patients with osteoporosis and it always occur in the subcapital region. We report a case of subcapital stress fracture of the femur occurred after internal fixation with compression hip screw of intertrochanteric femur fracture.

BACKGROUND: Although one hair usually arises from a single follicular opening in normal healthy subjects, we can see two or more hairs emerging from the single opening through close inspection. The latter is called "compound hair", described by Lowenthal in 1946, however, few reports on this have been made since. Histopatholoigcally two or more hairs which have an independant external root sheath arise from one follicular opening like its clinical appearance. We examined the distribution and density of compound hair in order to define its difference according to anatomical sites and aging process. OBJECTIVE AND METHOD: We counted the number of hairs in the circle(2 cm in diameter) at te frontal, temporal and occipital scalp of 24 old young men(22.5+/-2.0 years old) and 24 old men(64.4+/-12.9 years old), respectively. RESULTS: The summated number of grouped hair, which was mostly regarded at compound hair, was greater in the young group than in old group in the frontal area, but was smaller in young group than in old group in from the temporal and occipital areas. The proportion of grouped hair to total hair in the older group was lower in the frontal area, but higher in the temporal and occipital areas(p<0.05, p<0.01) according to aging process, however, no significant change was seen between the frontal area and the sum of single hair to compound hair was significantly decreased in the temporal and occipital areas(p<0.05, p<0.01) according to aging process, however, no significant change was seen between the frontal area and the sum of the three tested areas. CONCLUSION: Compound hairs are observed frequently on the scalp of normal healthy subjects and are most frequently seen on the occipital scalp in both of the young and old.
