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.

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.
