Cholelithiasis and cholecystitis frequently necessitate cholecystectomy. Experience is increasing with laparoscopic cholecystectomy, a technique that avoids much of the morbidity, pain, prolonged hospital day, and recovery complications associated with the traditional approach. And the safety of laparoscopic cholecystectomy was confirmed. Besides appendectomy, cholecystectomy is the second most common nonobstetric procedure performed in pregnant women. We have performed one case of a successful laparoscopic cholecystectomy in the second trimester of pregnancy. Pregnancy was once a contraindication of laparoscopic operation, but no longer.

The rim sign in renovascular compromise may be defined as a thin nephrographic rim outlinning a kidney with another wise faint nephrogram. Renal infarction with gelform and blood clots was induced experimentally in 5 dogsand high dose IVP and CT were performed to evaluate renal cortical rim sign after renal infarction. One expireddue to anesthetic technical failure, and one was embolized partially. So we could be obtain the result on 3 dogs.The reults were as follows; 1. The high dose IVP films show cortical rim sign on 24 hrs and 72 hrs films in twodogs. The CT films show rim sign in 3 dogs. 2. The rim sign may be visualized, if the renal artery is occuludedenough to drop perfusion presssure below the authoregulatory range. 3. The high dose IVP and early nephrogramphase are necessary for the rim sign.

Sebaceous adenoma is a benign organoid tumor of proliferating, incornpletely differentiated sebaceous glands. We report a case of sebaceous adenoma in a 15-year-old male. He had a 1.7 x 2.2 cm sized, asymptomatic, srnooth, round, raised, firm, reddish tumor on the left quadrant of abdomen. Histopathologically, the tumor was composed of lobules of irregular size and shape, and sharply demarcated from the surrounding tissue, The most lobules showed undifferentiated germinative and mature sebaceous cells in about equal number. Sebaceous cells in lobules were stained for prekeratin by means of avidin-biotin-peroxidase complex method. Ten months after surgical excision there was no evidence of recurrence.

Candidiasis is the most common fungal infection complicating the course of patients with hematologic malignant neoplasms. Although widespread organ involvement is characteristic of disseminated candidiasis, reports of skin are rare. Reports describing typical clinical and histopathological finding of cutaneous lesions are very important since it may enable a diagnosis of disseminated candidiasis to be made and thus antifungal therapy can be initiated earlier. A 50-year-old housewife was admitted with a 5-month history of fatigue and easy bruising. She was diagnosed as ha.ving acute myelocytic leukemia and treatment was begun with daunorubicin and cytosin, arabinoside. Eight days after the start of chemotherapy, she developed a fever and generalized tender well demacated erythematous to purplish papulonodular eruption. A biopsy specimen from the skin lesion showed perivascular mononuclear cell infiltration and spore and pseudohypae v,rere found within the dermis and subcutis in PAS stain. Cultures of one skin biopsy specimen and one of four blood sarnples grew Candida tropicalis. The patient was treated with intravenous amphotericin B for disseminated candidiasis. On the tenth day of antifun gal therapy, she developed cardiopulmonary arrest and died.

Seven cases of retroperitoneal laparoscopic lumbar sympathectomy were successfully performed in 10 patients with ischemic lesions of lower limbs or ischemic rest pain between June, 1996 and October, 1996. All patients had nonreconstructable distal vessels on femoral angiogram. Our techniques of retroperitoneal laparoscopic lumbar sympathectomy is described in detail. Procedure offers the advantage of minimally invasive surgery and can be performed more efficiently as the experience of the surgeon accumulates.

This study aimed to investigate the existence of GABA receptor and the mechanisms of action of GABA and diazepam of the trachealis muscle isolated from dog. Horizontal muscle strips of 2mm×15mm were prepared from canine trachea, and isometric myography in isolated muscle chamber bubbled with 95/5%-O₂/CO₂ at 36℃, at the pH of 7.4 was performed. Muscle strips contracted responding to the electrical field stimulation (ESP) by 2~20 Hz, 20 msec, monophasic square wave of 60 VDC. GABA and diazepam suppressed the EFS-induced contractions to the similar extent, significantly. (p<0.05). Bicuculline, a GABA(A) receptor antagonist blocked both GABA- and diazepam-inhibitions; but DAVA, a GABA(B) receptor antagoinst did not affect either of them. These results suggest than in the canine trachealis muscle, there may be only GABA(A) receptor, and GABA and diazepam inhibit the contractility via GABA(A) receptor.

PURPOSE: Ocular sparganosis has not been reported in Korea and 5 cases have been reported sporadically worldwide. Among these, 2 cases were found under the conjunctiva. We reported the first Korean case of ocular sparganosis manifesting as a subconjunctival mass. CASE: A 29-year-old man was presented to remove sunconjunctival mass in his left eye for cosmetic purpose. His ocular findings were normal except 0.5 x 0.5 mm sized subconjunctival mass. The surgically excised mass was suspected to have a parasite grossly. Sparganum was identified under microscopic examination after hematoxylin-eosin staining. CONCLUSIONS: The morphologic state of mumified parasite under microscope was plerocercoid phase of spargaum. His ocular movement and visual acuity remained normal after excision of the mass.
