Present trial was carried out to evaluate the anthelmintic efficacy of oxantel/pyrantel tablets against intestinal nematode infections, and to determine the efficacy of oxantel tablels against Trichuris infection. A total of 34 subjects with the mixed infections were treated with oxantel/pyrantel tablets (100 mg/tablet each) in a single dose of 15 mg/kg body weight, and another group of 22 Trichuris infected cases received oxantel pamoate tablets (125 mg/tablet) in a single dose of 15 mg/kg. All stool examinations were done before the treatment and 3 weeks after the treatment. The cellophane thick smear (Kato's technique) and Stoll's dilution egg counting method were employed. The results of the trial were summarized as follows: The cure rates (egg negative conversion rates) and egg reduction rates for oxantel/pyrantel tablets were 85.3 percent and 97 percent in trichuriasis, 100 percent each in ascariasis and ancylostomiasis. The oxantel tablet treated group demonstrated a cure rate of 90.9 percent and an egg reduction rate of 96.3 percent in the treatment of Trichuris. There were no detectable objective and subjective side effects in this trial. Both oxantel/pyrantel and oxantel pamoate tablets were readily accepted and well tolerated.

The diagnostic possibility and the incidence of ectopic pregnancy are increasing due to several factor. Furthermore, radioimmunoassay of serum β-HCG and US make it possible to diagnose early before the tubal rupture. A conventional surgical approach has been considered as a choice of treatments. Until recent years, however, surgery may have considerable risk of infertility and sugical hazard. In view of the natural tendency of some ectopic pregnancies to terminate in tubal abortion or complete resorption, we tried to cure ectopic pregnancy with nonsurgical transcervical intervention. Five of 8 patients with unruptured tubal pregnancies, it was possible to inject PGF2a into the tubes or gestational sac. 4 of them were ended up with satisfactory reduction of serum β-HCG level and improvement of symptoms & signs. In only one patient, β-HCG level remained a high level continuously, so salpingectomy was done. As a result, we consider that fluoroscopy-guided transcervical interventional procedure is a useful treatment modality for early unruptured ectopic pregnancy.

OBJECTIVE: We aimed to evaluate the effects of different oxygen conditions (20% [high O₂], 5% [low O₂] and 5% decreased to 2% [dynamic O₂]) on mouse pre- and peri-implantation development using a novel double-channel gas supply (DCGS) incubator (CNC Biotech Inc.) to alter the oxygen concentration during in vitro culture.METHODS: The high-O₂ and low-O₂ groups were cultured from the one-cell to the blastocyst stage under 20% and 5% oxygen concentrations, respectively. In the dynamic-O₂ group, mouse embryos were cultured from the one-cell to the morula stage under 5% O₂ for 3 days, followed by culture under 2% O₂ to the blastocyst stage. To evaluate peri-implantation development, the blastocysts from the three groups were individually transferred to a fibronectin-coated dish and cultured to the outgrowth stage in droplets.RESULTS: The blastocyst formation rate was significantly higher in the low-O₂ and dynamic-O₂ groups than in the high-O₂ group. The total cell number was significantly higher in the dynamic-O₂ group than in the low-O₂ and high-O₂ groups. Additionally, the apoptotic index was significantly lower in the low-O₂ and dynamic-O₂ groups than in the high-O₂ group. The trophoblast outgrowth rate and spread area were significantly higher in the low-O₂ and dynamic-O₂ groups than in the high-O₂ group.CONCLUSION: Our results showed that a dynamic oxygen concentration (decreasing from 5% to 2%) had beneficial effects on mouse pre- and peri-implantation development. Optimized, dynamic changing of oxygen concentrations using the novel DCGS incubator could improve the developmental competence of in vitro cultured embryos in a human in vitro fertilization and embryo transfer program.

Although crystalloid solutions such as Ringer's lactate have become the standard for initial volume replacement after hemorrhage, it is controversy whether this fluid alone restores and maintains the depressed physiologic function after severe hemorrhage. Six anesthetized dogs were bled(35ml/kg) and resuscitated with Ringers lactate solution (100 ml/kg). Physiologic variables are measured initialy, after hemorrhage, after resucitation. Compared with initial value, after resuscitation data show marked reduction in hemoglobin, oxygen carrying capacity, vascular resistance, and electrolyte. But cardiac output and blood gas analysis data was not changed. Prothrombin time and partial thromboplastin time was prolongated. From this study crystalloid resuscitation in severe hemorrhagic shock restore cardiac output and perfusion, but fail to maintain adequate oxygen carrying capacity.
