Since that first description of the so-called granular cell myoblastoma by Abrikossoff in 1926, it has been reported as occuring in many sites. This tumor is an unusual but not rare tumor. From the number of reviewed case reports(550) upto now, it appears that the occurence of multiple granular cell tumors (36) is much more common (7–16%) than traditionally believed. The precise histogenesis of this tumor is open to question. Most of this tumor is benign, but malignant ones have been reported. A case of malignant granular cell myoblastoma which was histologically proven and metastasized to the coracoid process of left scapula, the lung, and the skull, is presented with a brief of the literature.

BACKGROUND: The prevention of preterm deliveries still remains a major problem in ob-stetrics. The cause of preterm labor is poorly understood. Our purpose was to determine the risk factors for preterm labor associated with specific clinical and environmental factors. METHODS: Using a case-control design, 54 women with preterm labor and 134 controls with term labor, who were admitted to the department of Obstetrics and Gynecology, Dan- kook University Hospital from January, 1996 to August, 1996. The study groups were inte- rviewed and their medical records were reviewed. RESULTS: 1. There were no significant differences of maternal age, maternal weight at 20 weeks of gestation and maternal weight gain at the time of delivery. 2. There were no significant differences between housewives and working women. But the physical workload of the preterm labor group was significantly higher than the control group ( 16.0% vs. 4.0% ). 3. There were no significant differences in the smoking habit of mother or her husba- nd. The passive smoking of the preterm labor group was significantly higher than the con- trol group ( 43.8% vs. 26.8% ). 4. In vaginal bleeding at pregnancy, the preterm labor group was significantly higher than the control group ( 15.7% vs. 2.3% ). Especially, the third trimester vaginal bleeding of the preterm labor group was significantly higher than the control group. 5. There were no significant differences in the number of previous fullterm deliveries, previous abortions, and living children between two groups. The experience of the previous preterm deliveries of the preterm group was significantly higher than the control group ( 11. 5% vs. 0.8% ). 6. There were no significant differences of medications, consumption of alcohol, coffee, tea, green-tea, cola and nutritional beverages, the experiences of coitus, defecation numbers and accidents during pregnancy between two groups. 7. There were no significant differences in the plasma concentrations of hemoglobin, hematocrit, white blood cells, and in the blood pressure, and the body temperature between two groups. CONCLUSION: The risk factors of preterm labor were severe physical workload, vaginal bleeding at pregnancy, especially, the third trimester vaginal bleeding, and the experience of previous preterm deliveries.

Reviewing 16 patients of fractures and dislocations of the cervical spine treated and managed at Department of Orthopedic Surgery, Kyungpook National University Hospital from January 1963 to August 1970 We came to the following conclusions: 1. The incidence of trauma was high in the young men, most frequent in the 3rd and 4th decades. 2 Most of the injuries were the results of automobile accidents or of falls on the head and neck. 3. Twelve of sixteen patients had dislocations or subluxations associated with the fractures and the remainder of 16 had dislocations or subluxations without demonstrable fractures. These occurred most often at the level of the 5th and 6th cervical vertebra. 4. Twelve of sixteen patients had a total of demonstrable fractures, and compression of a vertebral body was the most common type of fracture. 5. Trauma to the head was the commonest associated injury. 6. Mild or severe cord damage signs had developed in 12 of 16 patients; a case who was assocated with severe cerebral damage was dead, 7 were quadriplegic and 4 returned to former professional life. The remainder of 16 had a good recovery without disability.

A case of testicular embryonal carcinoma developed in s cryptorchid testis is presented with a review of the literature. According to Campbell's series, the incidence of malignant cryptorchid testis was 11.6%. and his statistical evaluation was similar to Gilbert and Hamilton's series of 7,000 cases of testicular neoplasms where 840 tumors were developed in undescended testes(12%). Both authors agree that the chance of neoplastic development in a cryptorchid testis is approximately 48 times greater then that developing in a normally descended testis. Several cases of testicular tumor were reported sporadically in Korea, but malignant tumors in cryptorchism were rarely seen in the literatures Only two cases of malignant cryptorchid testis were already reported in Korea.

It has been well known that prutic skin diseases are very common among the chicken raisers. Authors visited three paultry farming area in Kyung Ki Province to observe the avian mite dermatitis among the workers and to collect the causative paultry mites during the period from March to September, 1982. At every paultry farming area, we chose two families to investigate every family member and to check the dermatitis correlated with the mite that we had collected from the samples of each house dust and hen-house dust. The result were summarized as follows; 1. Ornithonyssus sylviarum (Canestrini and Fanzago, 1877) was found in dust samples from two houses and two hen-houses. And Dermatophagoides species and Acarus siro (Linnaeus, 1758) were also collected from the other house and henhouse samples. 2. Three cases of avian mite dermatitis were found in one family, where O. syiviarum was collected in the dust samples from their house and hen-house.

The discovery and synthesis of vitamin D and the elucidation of the role of sunlight in the activation of the vitamin D precursors changed the syndromes of rickets from a therapeutic enigma to a socioeconomic and public health problem. Since Albright in 1937 first described vitamin D resistsnt rickets, which did not respond to treatment with the usual dose of vitamin D, it has progressively become a common form of rickets in practice. In addition, as the result of increasing understanding of renal physiology and careful investigation, a spectrum of renal tubular abnormalities have been identified which cause clinical rickets and which in many cases are insensitive to even large doses of vitamin D. We have reported a case of an unusual form of vitamin D resistant rickets which did not easily respond to treatment with high doses of vitamin D and was associated with hypocalcemia in multiple pathologic fractures in the lower extremities of the patient.

PURPOSE: Ion channels play key roles in determining smooth muscle tone by setting the membrane potential and allowing Ca2+ influx. Potassium channels may be important in modulating corporal smooth muscle tone. In this study, we investigated the effects of potassium channels in the rabbit corpus cavernosal smooth muscle by blocking them with various agents. MATERIALS AND METHODS: Strips of rabbit corpus cavernosum were prepared for mounting and isometric tension measurement in an organ bath. On cavernosal strips contracted with phenylephrine (PHE), sodium nitroprusside (SNP) was applied in increasing concentrations from 10(-7)M to 10(-4)M, causing dose-dependent relaxation. The effects of various potassium channel blockers on SNP-induced relaxation were then evaluated by measuring the tension of the cavernosal strips. The potassium channel blockers used were tetraethyl ammonium (TEA), charybdotoxin, gliben clamide, and apamin. RESULTS: The relaxation responses to SNP of the corporal preparations contracted in response to PHE were significantly attenuated by TEA (10(-2)M) and charybdotoxin (10(-7)M), with no significant difference observed between the two drugs. The SNP-induced relaxation responses were not significantly attenuated by glibenclamide (10(-5)M) or apamin (10(-5)M). CONCLUSIONS: These results suggest that maxi-K+ channels play an important role in corpus cavernosal relaxation. The KATP channel and small-conductance KCa channel are thought to be unrelated to corpus cavernosal smooth muscle relaxation.
