The purposes of this study were to test the negative association between schizophrenia and rheumatoid arthritis(RA) and to clarify the role of prolactin and estrogen as protective factors in this association. The author compared the prevalence rate of RA between 561 patients with schizophrenia and 222 patients with mood disorder. For investigating the role of estrogen and prolactin, the author checked the plasma prolactin and estradiol level in 80 patients with paranoid schizophrenia and 77 patients with RA. The results were as follows. 1) Epidemiological data The prevalence rate of RA in the schizophrenic group was 0/561 and that of RA in the mood disorder group was 2/222. To compare these results between two groups, the author applied the Binomial test using the average prevalence rate of RA(0.8%) in the general population as a reference rate. The prevalence rate of RA in the schizophrenic group was significantly lower than that of RA in the general population. However, the prevalence rate of RA in the mood disorder group was not significantly different to that of RA in the general population. 2) Comparison of plasma prolactin and estradiol level between two groups. The plasma level of prolactin in the schizophrenic group was significantly higher than that of prolactin in th RA group(p=0.000). However, the plasma level of estradiol in the schizophrenic group was significantly lower than that of estradiol in the RA group(p=0.017). These results were not consistent across gender. To contrast with the results in the female group, which were consistent with the results in the total subjects, for the male group, the plasma levels of prolactin and estradiol in the schizophrenic group were significantly higher than those of prolactin and estradiol in th RA group. These results support the results of previous studies which confirm the negative association between schizophrenia and RA. These results also suggest that the elevation of plasma prolactin level in the patient with schizophrenia has a antirheumatic effect while the elevation of plasma estradiol level in the patients with RA has a anti-schizophrenic effect, and that these effects act as a possible mechanism in the negative association between two disorders. However, these results suggest that this association is specific to female patients.

The Supracondylar fracture of the humerus is the most common elbow fracture in children. In general, accurate anatomic reductio, the least regional trauma as possible and the maintenance of the reduction are necessary to obtain excellent results. Lateral and posterior approach is commonly used method for the treatment of supracondylar fracture of the humerus in children. But lateral and posterior approach has some troubles in reduction of fracture and Kirschner wire fixation. From March 1988 to February 1993, seventeen supracondylar fractures of the humerus were treated by means of medial approach and followed from 8 monts to 13 months with an average 10 months. There were some advantages in medial approach. Reduction was easy and ulnar nerve was not damaged by medial approach at insertion of Kirschner wire and no more another incision. The results obtained are as follows. Postoperative vascular impairment or Volkmann's ischemia was not complicated and neurologic deficits accompanied with injury were all recovered completely. According to Mitchell and Adams' criteria, all had satisfactory results.

Cyclins are proteins that activate different cyclin-dependent kinases(CDKs) and promote the cell cycles. Their correlations with several human cancers have been identified. Cyclin E, as one of G1 cylins, produces DNA replication through the progression of cell cycle G1 --> S phase. In contrast, cyclin-dependent kinase inhibitors(CDKI) bound with cyclin E-cdk2 complex control the cell cycle and inhibit the cell proliferation. P21(WAF1) proteins, which are CDKIs, are transcripted by a p53 gene and participate in the cell cycle inhibition. Variant p53 proteins produced by a mutated p53 gene lose the ability to control of the cell cycle resulting in cell proliferation. This study is aimed to reveal the expressions of cyclin E, p21(WAF1) protein, p53 variant protein in colorectal adenomas and carcinomas, and also reveal their correlations in the process of carcinogenesis. Twenty-one colorectal adenomas or adenomatous polyps, and thirty colorectal carcinoma tissues were obtained by operative resections or endoscopic polypectomies. Immuno histochemical stains of the above-mentioned three proteins and a statistical analysis of their correlations were made. The results were as follows: 1. P21 proteins were expressed in the upper-one third layer of all normal colonic mucosa, but cyclin E and variant p53 protein were not identified. 2. Cyclin E was expressed in 23.8% of adenomas and 76.7% of carcinomas. Variant p53 protein was expressed in 71.4% of adenomas and 83.3% in carcinomas. The degree of positivity of variant p53 expression was correlated with cancer staging. P21 protein was expressed in all adenomas, similar to normal mucosa, but was not expressed in 43.3% of carcinomas. 3. Expression of cyclin E was increased as to the positivity of variant p53 proteins but the correlations of p21 proteins and cyclin E, and p21 proteins and variant p53 proteins were not identified. Cancer staging was not correlated with the expressions of the three proteins. In conclusion, it can be thought that the overexpression of cyclin E and variant p53 proteins, and the loss of p21 proteins are related with the colorectal carcinogenesis. We can also identify the relationship of cyclin E and variant p53 proteins.

PURPOSE: A wide variety of surgical materials have been used for blepharoptosis such as catgut, silicone, 4-0 nylon polyfilament cable-type ophthalmic suture (Supramid(R)), autogenous tendon (palmaris longus),banked sclera, dura mater, fascia lata, and temporalis fascia. The aim of this study was to evaluate the effect of frontalis suspensory surgery with temporalis fascia. METHODS: The authors studied 91 frontalis slings (71 patients) performed from 1993 to 1999 at our hospital for repair of blepharoptosis. Results with temporalis fascia (group A) as the suspensory material were compared to those with autogenous (group B) and preserved (group C) fascia lata. RESULTS: The success rates of group A (31 lids 21 patients), group B (28 lids 24 patients), group C (32lids 26 patients) were 80.6%, 75%, 78.1% respectively. But there was no statistically significant difference in each groups (P>0.05). CONCLUSIONS: We concluded that temporalis fascia for frontalis sling could be used as suspensory material successfully. Moreover, long term and further evaluations must be considered.
