Fractures of the body of the talus are extremely rare, constituting only about 0.1 percent of all fractures (Coltart 1952). Consequently, the prognostic problems have so far been elucidated only on the basis of few reports in the literature. The authors experienced an unusual type of the shearing fracture of the talar body with total disocation that the talar body was lying upside down in the ankle joint. Satisfactory results were obtained after follow up period of 20 months and some are reporting this case with bibliographic reviews.

OBJECTIVE: The effects on spermatogenesis by expression of vascular endothelial growth factor (VEGF) and endothelin-1 (ET-1) were investigated. MATERIALS AND METHODS: Testicular specimens were obtained from 40 infertile males due to primary testicular failure and from 10 fertile males with other urologic problems. The specimens of infertile males were devided into 4 groups according to histologic findings; Sertoli cell only syndrome (A), maturation arrest (B), hypospermatogenesis (C) and sloughing and disorganization (D). VEGF and ET-1 expression were detected with immunohistochemical stain. RESULTS: VEGF expression on Leydig cell was detected in all cases. But, VEGF expression rates on germ cell were significantly higher in infertile group B, C, D compared to that of the control group (p<0.05). ET-1 expression rates on Leydig cell was significantly lower in all infertile group compared to that of the control group (p<0.05). But, ET-1 expression rates on Sertoli cell was significantly higher in all infertile group compared to that of the control group (p>0.05). In germ cell of infertile group, LH, FSH and prolactin were significantly decreased, and estradiol is increased in positive stain group on ET-1 immunohistochemical stain (p<0.05). VEGF and ET-1 expression were not correlated mean seminiferous tubule diameter (p>0.05). CONCLUSIONS: Abnormal spermatogenesis would be reflected in VEGF expression in germ cell.

We studied the incidence and morphological variation of the metopic suture in Korean. Ninety-six adult Korean dried skulls and 141 cases of antero-posterior skull roentgenograms from age of 1 month to 80years old. We divided metopic suture into complete and incomplete type. Incidence of complete type was 8.3% in dried skulls. In roentgenograms the incidence was decreased according to aging, especially around 6-8 years old, and over 20 years old age group the incidence was 4.0%. The incidence of incomplete type was 32.3%.

Serum levels of HDL-cholesterol, triglyceride and total cholesterol were measured in 107 normal Koreans and in 327 patients; 66 patients with hypertension, 34 patients with coronary heart disease, 45 patients with cerebral thrombosis, 18 patients with nephrotic syndrome, and 164 patients with diabetes mellitus. Patterns of serum lipoprotein fractions were also investigated by agarose gel electrophoresis in 41 normal Koreans and in 72 patients; 14 patients with hypertension, 10 patients with coronary heart disease, 19 patients with cerebral thrombosis, 7 patients with nephrotic syndrome, and 22 patients with diaebetes mellitus. The results are summarized as follows; 1. Mean values of serum HDL-cholesterol, triglyceride and cholesterol in normal Koreans were 52.2+/-12.4mg/100ml, 110.6+/-31.6mg/100ml and 175.3+/-21.4mg/100ml respectively. No significant difference in mean value of serum HDL-cholesterol was observed between Korean males and females. 2. In Korean females serum, HDL-cholesterol level showed peak values in the fifth decade, but no significant difference with aging was observed in Korean males. 3. Serum HDL-cholesterol levels were significantly decreased in patients with hypertension, coronary heart disease, cerebral thrombosis, and in male diabetic patients with complication. 4. Serum triglyceride levels were significantly increased in all the disease groups, and serum cholesterol levels were significantly increased in all the disease groups except cerebral thrombosis. 5. Mean values of alpha-lipoprotein, pre-beta-lipoprotein and beta-lipoprotein fraction ratios in normal Koreans were 28.9+/-7.5%, 14.9+/-4.9% and 56.2+/-8.1% respectively. 6. Seum alpha-lipoprotein fraction ratio was significantly decreased in relatively advanced hypertensive patients. Pre-beta-lipoprotein fraction ratio tends to be increased in patients with hypertension, cerebral thrombosis, nephrotic syndrome and in diabetic patients with complications, and beta-lipoprotein fraction ratio tends to be increased in patients with hypertension, coronary heart disease and nephrotic syndrome, but those were not statistically significant.

One hundred seven consecutive patients aged 3 years to 34 years with simple ventricular septal defect were prospectively investigated with 2-dimensional Doppler echocardiography to assess the echocardiographic criteriae in defining the anatomic site of the VSD. The anatomy was confirmed in all patients at operation. Two-dimensional Doppler echocardiography correctly categorized the site and extension of VSDs in 104 of 107(97%). All doubly committed subarterial VSDs were correctly diagnosed as an area of discontinuity beneath the pulmonary valve in the parasternal short-axis plane taken at the aortic root level. Forty eight of 49 perimembranous VSDs with infundibular extension showed an area of discontinuity beneath the right aortic cusp in the parasternal long axis plane of the left ventricle. Of 17 perimembranous VSDs with trabecular extension, 16 had an area of discontinuity around the medial papillary muscle in the short axis plane taken at the level of high left ventricular outflow tract(LVOT). All 5 perimembranous VSDs with inlet extension showed an area of discontinuity adjacent to the septal leaflet attachment in the short axis plane taken at the level of high LVOT. One muscular trabecular VSD was categorized correctly by the short axis view and the apical 4-chamber view. Thus, these 2-dimensional Doppler echocardiographic criteriae are a simple and reliable in identifying the anatomic site of VSDs.
