There is increasing evidence that inactivation of tumor-suppressor genes can promote tumor growth. Retinoblastoma protein (pRb) is the product of the retinoblastoma gene located on chromosome 13q14. pRb negatively regulates cell growth when functioning normally. Mutational inactivation of the Rb gene has been observed in retinoblastomas, osteosarcomas and soft tissue sarcomas. Recently, several other human cancers have also been shown to carry abnormalities of the Rb gene. The potential role of the Rb gene in cutaneous squamous cell carcinomas (SCCs) and basal cell caicinomas (BCCs), has not been determined and was the focus of this study. Immunohistochemical expression of pRb in 16 cutaneous SCCs and 17 BCCs was examined. The expression of PCNA was studied in parallel to assess the cellular proliferation rate in these lesions. The pRb and PCNA immunoreactivity were localized to the nuclei of tumor cells. A few pRb and PCNA positive cells were seen in normal squamous epithelium, sebaceous glands, sweat glands and hair follicles. The loss of expression of pRb was seen in 3 of 16 SCCs(18.8%) and 6 of 17 BCCs (35.3%). PCNA immunoreactivity was slightly high in pRb-negative or lower-positive cases. PCNA immunoreactivity was similar to that produced by pRb in some cases. These results suggest that mutational inactivation of the Rb gene may be related to the carcinogenesis of cutaneous SCC and BCC, though the frequency is relatively low.

We know that irrigating fluid used during transurethral resection of prostate (TURP) is rapidly absorbed through open prostatic venous channels in large amount. The TURP syndrome is symptom complex of hypervolemia & hyponatremia (below 130 mEq/1) due to absorption of irrigating fluid. We studied the change of serum sodium, potassium and symptom of hypervolemia during the perioperative period, in 35 patients undergoning TURP. The aim of this clinical study was to examine the possible relation between the irrigating fluid absorption & the development of hyponatremia after TURP. The results were as follow. 1) Though p value was not acceptable, there waa numerical correlation between the weight of resected prostate and the amount of irrigating fluid. 2) TURP syndrome and severe sodium change were not reported in our studiea, 3) We through the cause of above results that operation time & minimal use of irrigating fluid & minimal bleeding due to advanced operative technique, adequate fluid therapy, and intenaive monitoring of vital sign & physiologic change of patients.

BACKGROUND: Cardiac troponin T (cTnT) is a new serological marker for use as a diagnostic toots for acute myocardial infarction (AMI). This study was designed to evaluate tee diagnostic efficiency of troponin T in AMI. METHODS: We determined the reference range of troponin T in 20 healthy adults without previous cardiovascular diseases and chest pain. We evaluated troponin-T, CK, LD, AST and CK-MB in serum of 13 AMI and 5 angina pectoris patients. The patients were arrived at the hospital within 3 hours after onset of (most recent) acute symptoms. Samples were drawn individually at the times of 0, 1, 3, 7, 18 and 24 hours after admission and continued at 6-h intervals for 2 days and 24-h intervals fort 2 weeks. Troponin T was determined by an enzyme-linked immuno-sorbent assay (one step sandwich assay) on an ES-300 analyzer. RESULTS: We found that serum troponin-T concentrations in healthy control adults were below 0.07microgram/L. The peak level of troponin-T concentration of patients with AMI was 22.0microgram/L, mean value, at 7 hours after admission and showed 110 times its discrimination limit value (0.2microgram/L). CK-MB value was normalized within 3 days after admission, but cTnT value remained high above its discrimination limit value until 2 weeks after admission during this study. CONCLUSIONS: The data indicate that the measurement of serum cTnT improves efficiency of serological testings of AMI as compared with conventionally used cardiac enzymes.

Facial clefts are uncommon congenital deformities in comparison to the clefts of the lip and palate. the clinical expression of the craniofacial clefts is highly variable. the face can be marred by a faint expression of the cleft or be disfigured by a full representation of the defect. the extent of the soft tissue and skeletal components is also variable, and they are seldom affected to an equal degree. Generally, discription of the clefts are based on the bony malformation, since the skeletal landmarks tend to be more constant. I report six cases of rare craniofacial clefts that I recently experienced. the soft tissue repair was accomplished with local flaps from cheek, eyelid and nose. Additional vertical length was obtained from the lower Z-plasty flaps in the sutures. the coloboma was corrected with local flaps and a cartilage graft, the depression of cheek with a dermofat graft, and the macrostomia with the repositioning of orbicularls oris muscle and a Z-plasty. the results were cosmetically acceptable.
