The authors carried out histochemical studies on Clonorchis sinensis, especially, histochemical demonstration of carbonic anhydrase activity. Kurada's method was applied for the histochemicl staining in this study. The result obtained were summerized as follows : Carbonic anhydrase activity was intensely positive in oral sucker cells, reticular tissue cells, epithelium of the intestine and testes, more or less intensely positive in vitelline gland cells and yolk of eggs as well.

OBJECTIVE: We describe our clinical experiences and outcomes in patients who had thromboembolic complications occurring during endovascular treatment of intracerebral aneurysms with a review of the literature. The types of thromboembolic complications were divided and the treatment modalities for each type were described. METHODS: Between August 2004 and March 2009 we performed endovascular embolization with Guglielmi detachable coils for 173 patients with 189 cerebral aneurysms, including ruptured and unruptured aneurysms at our hospital. Sixty-eight patients were males and 105 patients were females. The age of patients ranged from 22-82 years (average, 58.8 years). We retrospectively evaluated this group with regard to complication rates and outcomes. The types of thromboembolic complications were classified into the following three categories: mechanical obstruction, distal embolic stroke, and stent-induced complications, which corresponded to types I, II, and III, respectively. A comparison of the clinical results was made for each type of complication. RESULTS: Only eight patients had a thromboembolic complication during or after a procedure (4.6%). Of the eight patients, two had a mechanical obstruction as the causative factor; the other three patients had distal embolic stroke as the causative factor. The remaining three patients had stent-induced complications. In cases of mechanical obstruction, recanalization occurred due to the use of intra-arterial thrombolytic agents in one of two patients. Nevertheless, a poor prognosis was seen. In the cases of stent-induced complications, in one of three patients in whom a thrombus developed following stent insertion, a middle cerebral artery territory infarct developed with a poor prognosis despite the use of wiring and an intra-arterial thrombolytic agent. In the cases of distal embolic stroke, all three patients achieved good results following the use of antiplatelet agents. CONCLUSION: Treatment for thromboemboic complications due to mechanical obstruction and stent-induced complications include antiplatelet and intra-arterial thrombolytic agents; however, this cannot guarantee a sufficient extent of effectiveness. Therefore, active treatments, such as balloon angioplasty, stent insertion, and clot extraction, are helpful.

BACKGROUND: The patient's position cannot be changed in the hyperbaric spinal anesthesia until the anesthesia level is fixed because gravity has an effect on the spread of hyperbaric solutions. The isobaric spinal anesthesia has the advantage that the patient's position can be changed soon after drug is injected into the subarachnoid space because gravity has no effect on the spread of isobaric solutions. Most studies of isobaric spinal anesthesia had been made using plain bupivacaine. In this study, effects of drug dose, volume, and concentration on the spinal anesthesia with isobaric tetracaine were investigated. METHODS: Eighty patients were randomly allocated to four groups: 1), group 1 received 1% tetracaine 14mg, 1.4ml (N=20), 2), group 2 received 0.74% tetracaine 14mg, 1.9ml (n=20), 3), group 3 received 0.5% tetracaine 14mg, 2.8ml (n=20), 4), group 4 received 1% tetracaine 19mg, 1.9ml (n=20). Drugs were administered in lateral position at L3~4 level. Neural block was assessed by pinprick. Changes of analgesic level were evaluated with time. RESULTS: Peak analgesic level of group 4 was higher than that of group 2 after 12 minutes and no difference in analgesic level between group 1, 2, and 3 after 18 minutes. Group 4 resulted in longer duration and a higher peak level of sensory block than group 2. CONCLUSIONS: In spinal anesthesia with isobaric tetracaine, the volume is the major factor affecting initial spread of isobaric tetracaine and the dosage was the major factor affecting peak level. High concentration results in longer duration, and higher peak level.

OBJECTIVE: To evaluate the relationship between uterine weight and morbidity in women undergoing vaginal total hysterectomy. METHODS: A retrospective chart review of 549 cases of patients with vaginal totoal hysterectomy was performed. Patients included in this study underwent vaginal total hysterectomy as benign uterine tumors at Kangnam Sacred Heart Hospital, Hallym University, Seoul, Korea from June 2003 through June 2004. These patients were stratified into four groups; Group I patients with uterine weight of <180 gm (n=132), Group II patients with uterine weight of between 180 gm to 280 gm (n=238), Group III 280 gm to 380 gm (n=100), Group IV patients with uterine weight of >380 gm (n=79). The groups were compared as regard age, paturity, previous pelvic operations, postoperative discharge day, postoperation hemoglobin change, operation time, postoperative complications. RESULTS: There was no significant difference between the four groups with repect to postoperative discharge day (Mean=9.08 day), concurrent surgical procedure, age (M=45.96 years old), parturity (M=1.88). The overall complication rate was not significantly different (postoperation hemoglobin change (M=1.25), Complication). But the morcellation rate increased 8.33% in group I, 34.18% in group II, 55% in group III, 83.5% in group IV, respectively. The operation time prolonged as uterus weight increased.; 73 minutes in group I, 79 minutes in group II, 85 minutes in group III, 91 minutes in group IV. CONCLUSION: The vaginal total hysterectomy can be performed successfully in case of greatly enlarged uterus. Uterus enlargement is not an absolute contraindication.

This study was performed to evaluate the effect of topical and intravenous heparin on thrombosis and patency in the microvascular anastomosis of the traumatized veins. Nine white rabbits weighing about 2kg were used. After exposure of both femoral veins, the veins were crushed by the jaws of smooth needle holder in order to create a thrombosis model. Transectional incision was made in the vein. The animals were then divided into 3 groups based on the administration method of heparin: 1) Experimental Group I, topical irrigation of lumen with heparin saline solution (n=6); 2) Experimental Group 2, topical irrigation of lumen with heparin saline solution and intravenous injection of heparin (0.75 mg/kg) via the marginal ear vein for 3 days; 3) Control Group, topical irrigation of lumen with saline solution (n=6). The patency was evaluated with empty-and-refill test and thrombus formation was judged by surgical microscope. The results were as follows: 1. Thirty minutes after microvascular anastomosis, the patency fall Experimental Groups was better than Control group. However, there was no significant difference among groups. 2. Three days after anastomosis, the patency of all Experimental Groups was much more improved than that of Control Group (P<0.05). There was no significant difference between Experimental Group 1 and 2. 3. Three days after anastomosis, the amount of thrombus in all Experimental Groups was much less than that of Control Group (P<0.05). 4. In histologic findings a lot of luminal thrombus were observed around sutured area in Control Groups. Few luminal thrombus was observed in all Experimental Groups. Mild necrosis in the vessel wall was observed around sutured area in all specimens. These results indicate that topical irrigation of heparin may improve the patency and inhibit the formation thrombus in the microvascular anastomosis of the traumatized veins.
