A total of 48 subjects harbouring Trichuris trichiura, Ascaris lumbricoides, hookworm and/or Enterobius vermicularis were treated with oxantel/pyrantel pamoate tablets (100 mg of each) in a single dose of 20 mg base per kg of body weight. In all 37 cases of A. lumbricoides and 8 cases of A. duodenale infections cured completely, and the mean recovered worm-load was 3.8 with a range of 1-21 and 5.8 with a range of 3-9 respectively. In T. trichiura infection, 32(71.1%) of 45 cases cured completely and the average egg reduction rate was 90.8 per cent. The mean recovered worm-load was 14.6 with a rnage of 1-77 worms. On the other hand, in E. vermicularis infection, 37 (84.1 %) of 44 patients were negative eggs by anal swab tests on the 10 to 11th days and 27 (61.4%) on the 20 to 21st days after treatment. The mean recovered worm-load was 17.7 with a range of 1-62. Only one patient with Trichostrongylus orientalis treated with this drug showed no eggs in his stools throughout the post-treatment examinations. Side effects were not noted in all treated cases. These findings demonstrate that a single dose of oxantel/pyrantel pamoate tablets can be considered a drug of choice for multiple infections with these nematodes.

Protein expression patterns of matrix metalloproteinases (MMPs) were examined in mouse reproductive organs during estrous cycle. Estrous cycle was classified into diestrus, proestrus, estrus or metestus and MMP expression was analyzed by zymography using gelatin as a substrate. Uterine fluid (UF) obtained both at diestrus and proestrus exhibited 4 major MMPs including 106kDa, 64kDa, 62kDa and 59kDa gelatinases. However, in UF at estrus, the gelatinolytic activity of 64kDa MMP disappeared and that of 106kDa and 62kDa MMPs dramatically decreased. At metestrus, 64kDa MMP activity reappeared and 106kDa and 62kDa MMP exhibited increased activities such that the band intensity of 106kDa was comparable to that in UF at diestrus. Gelatinolytic activity of 59kDa MMP was not changed throughout the cycle. Both ovarian and oviductal tissue homogenate revealed 4 MMPs which corresponded to the 4 MMPs of UF. However, unlike UF MMPs, gelatinolytic activity of these MMPs did not show distinct changes throughout the cycle. Either an inhibitor of MMP, 1, 10-phenanthroline, or a metal chelator, EDTA, abolished the appearance of the above MMP activities in gelatinated gel whereas a serine proteinase inhibitor, phenylmethylsulfonyl fluoride, failed to inhibit the appearance of MMP activities, proving that gelatinolytic activity of the above reproductive tissues were due to the enzymatic activity of MMP. When gelatinolytic activity of mouse serum was examined, it revealed 5 MMPs (131kDa, 106kDa, 89kDa, 64kDa and 62kDa bands) and one gelatinase (84kDa) band. From these results, it is concluded that the protein expression of MMPs of mouse reproductive organs, particularly uterus, is temporally regulated during estrous cycle and uterine 106kDa, 64kDa and 62kDa MMP,3 are suggested to play an important role in cyclic tissue remodeling of mouse uterus.

A 18-month-old girl was seen because of an yellowish brown papular eruptions on the face, earlobes and neck of one year duration. A skin biopsy specimen revealed circumscribed cellular infiltrates composed of predorninantly pleornorphic histiocytes. Electron microscopy of biopsy material disclosed numerous worm like particles and coated vescles in limited area of the cell cytoplasm, consistent with the findinga described in benign cephalic histiocytosis. After six months of her first visit, the individual papules became flattened.

BACKGROUND: The potential adverse effects of ketamine in neurosurgical anesthesia have been well established. However, the effects of ketamine on intracranial pressure (ICP) and hemodynamics during general anesthesia remain unclear. The purpose of this study was to assess the effects of ketamine on hemodynamics and ICP in anesthetized, ventilated rabbits. METHODS: Thirty rabbits were divided into three groups: Group 1 (n=10) received 1 ml/kg normal saline iv; Group 2 (n=10) received 0.5 mg/kg ketamine iv; Group 3 (n=10) received 1.0 mg/kg ketamine iv. After induction with thiopental, anesthesia was maintained with isoflurane and nitrous oxide in oxygen. During controlled ventilation, ICP, mean arterial pressure (MAP), cerebral perfusion pressure (CPP) and heart rate (HR) were measured. The ICP was measured using Ladd ICP monitoring system. All variables were evaluated at baseline and for 30 min following ketamine. RESULTS: In group 1, ICP, MAP, CPP and HR were unchanged over the course of the study. In group 2, ICP, MAP and CPP were unchanged. HR increased at 1, 3 and 5 min (p<0.01), 10 and 20 min (p<0.05) after injection. In group 3, ICP, MAP and CPP increased at 1 and 3 min (p<0.01) after injection. HR increased at 1, 3 and 10 min (p<0.01), 5 min (p<0.05) after injection. CONCLUSIONS: These results suggest that 0.5 and 1.0 mg/kg of ketamine don't significantly affect the hemodynamics and ICP in anesthetized, mechanically ventilated rabbits.

Most obviuos will be the several anatomic differences between the proximal femur of the child and the adult. Fractures of the femoral neck in the children are extremely rsre and usually are the result of severe trauma in 80% of the cases. This accounts for the high frequency of serious associated injuries. In this injury the vascular anatomy changing with age, continuing growth potential and the effect of deforming forces play critical roles in high complication rate and these make treatment difficult. But still any secure guidelines for the treatment of this injury are not established and this is a field which requires more active research and further progress in future. 26 cases treated at Paik Hospital from Jan. 1979 to June 1988 were analyzed in clinical and radiological aspect and the following results were obtained. 1. The commonest type was Cervicotrochanteric fracture in 13 cases(50%),displaced one 21 cases. 2. In Transepiphyseal, Transcervical and Cervicotrochanteric fracture by early reduction and internal fixation, and in Intertrochanteric fracture by conservative treatment we gained satisfactory results. 3. We experienced 2 cases of coxa vara in nonthreaded pin used cases, 4 cases of premature epiphseal closure and 4 cases of avascular necrosis in threaded pin used ones. 4. Complications were developed in 13 cases (50%). These were 5 cases of coxa vara(19.2%) 4 cases of premature epiphyseal closure (15.4%) and 4 cases of avascul necrosis (15.4%). 5. Avascykar necrosis was developed in displaced fracture of Transcervical or Cervico- trochanteric fracture beyond postoperative 1 year. So. we recommend periodic long follow up for evaluation of avascular necrosis.

Familial hemophagocytic lymphohistiocytosis (FHL) is a rare disease characterized by fever, hepatosplenomegaly, cytopenia and non-malignant lymphohistiocytic infiltration with hemophagocytosis in reticulendothelial organs. We experienced three cases of FHL in identical male twins and their younger brother who presented with fever and severe hepatosplenomegaly. Cytopenia, elevated serum transaminase and low serum albumin levels, hypertriglyceridemia were common laboratory findings of them. One of them showed markedly decreased phytohemagglutinin induced lymphocyte proliferation and reversed CD4/CD8 ratio (0.52) in flowcytometric lymphocyte subset analysis. Aspirate of bone marrow revealed typical features consistent with FHL in two of them. In spite of recent therapeutic approaches, none of them survived.

PURPOSE: To assess the results and effectiveness of a small incision technique for ptosis repair. METHODS: Twenty three ptotic eyelids of 17 patients were repaired through a small incision between March 2005 and December 2005. Levator function and pre- and postoperative upper eyelid marginal reflex distances (MRD1) were checked. The small incision was executed on the eyelid crease, with a length of approximately 10.0~12.0 mm. Two 6-0 Ethilon stitches were placed to the tarsus after detecting levator aponeurosis with a Desmarres retractor. RESULTS: Of the 32eyes, 9 eyes had congenital ptosis and 23 eyes had acquired ptosis. The mean follow-up time was 12.1+/-3.4 months, with a levator function of 7.6+/-2.1 mm, preoperative MRD1 of 0.2+/-0.4 mm, and postoperative MRD1 of 2.6+/-0.3 mm. Two eyelids remained mildly undercorrected and required an additional operation. CONCLUSIONS: The small incision technique for ptosis correction is safe and precise, allowing more rapid recovery from surgery. The Desmarres retractor allows the levator to be found easily without complications. In addition, the small incision technique for levator repair is useful for congenital ptosis with good levator function as well as acquired ptosis.

PURPOSE: To evaluate the clinical efficacy of a reverse eyelid splitting technique that we performed in cases of trichiasis or distichiasis combined with entropion. METHODS: The study comprised 43 eyes of 31 patients with trichiasis or distichiasis combined with entropion treated from November 2004 to December 2005. After skin incision, the muscular layer and tarsus were reversely dissected to find abnormal follicles. The abnormal hair follicle was cauterized under the muscular layer, and 2~3 rotating sutures were done with Ethilon 6-0 to fix the tarsus and skin. Success was defined as having the meibomian gland located in front of the junction of skin and mucosa, without an abnormal hair protruding into the eye for at least three months. RESULTS: Fifteen patients were male and sixteen patients were female. The mean age was 62.1+/-15.2 years. The patients were followed up for an average of 12.4+/-2.0 months after surgery. Surgery was successful in 74.4% (32 of the 43 eyelids) of the cases, and the recurrence rate was 25.6% (11 of the 43 eyelids). No severe complications occurred, such as infection, hemorrhage, wound dehiscence, or granuloma. However, foreign body sensation (1 eye) and eyelid notch (l eye) did occur. CONCLUSIONS: This reverse eyelid splitting technique produced satisfactory results in both cosmetic and functional aspects. Moreover, it resulted in a low recurrence rate and low complication rate in patients with trichiasis or distichiasis combined with entropion.
