Effect of varying hematocrit ratio on the gastric acid production was studied in the heart-stomach preparation of the frog. When the hematocrit ratio was raised by injecting packed red blood cells obtained from the same species of frog, the acid production was increased significantly as compared to the low hematocrit group in which hematocrit ratio was lowered by injecting frog's normal saline. When a small amount of histamine was added to the medium of 25degree C, the acid production was increased in all cases, but the difference in the acid production between the high and the low hematocrit groups was abolished. However, when the temperature of the medium was lowered to 15degree C, the differences in the acid production between the two groups became significant. When a large amount of acetazolamide was added to the medium at 25degree C, the acid production was decreased significantly in both groups without showing a significant difference between the two groups. The reason(s) responsible for the increased acid production in the high hematocrit group was discussed.

A prospective study was initiated to compare maternal serum concentration of CA-125 during the first trimester of normal and abnormal pregnancies. Serum specimens were obtained from 87 women with a normal intrauterine pregnancy and 47 women with abnormal pregnancies which were ended in spontaneo abortion or pathologically confirmed to be missed abortion. In normal pregnancies, the mean serum CA-125 concentrations were increased significantly from amenorhea 6 weeks (139.838.7 IU/ml), and were higher statistically than the values tested in the same weeks of abnormal pregnancies. In abnormal pregnancies serum CA-125 concentations were relatively lower than those of normal pregnancies. But these differences were not statistically significant except the values tested in amenorhea 6weeks. So serum levels of CA-125 may not be proved useful in monitoring of early pregnancies outcome.

Aniskiasis is caused by the accidental infestation of human by larvae of marine mammals found in saltwater fish and squid. The clinical picture may be severe enough to stimulate an acute surgical abdomen. More commonly, colicky pain, diffuse abdominal tenderness, nausea, vomiting, fever, and leukocytosis are seen. Gastroscopically, 2-to 4-cm larvae can be seen penetrating the mucosa. More characteristically, the larvae burrow into the mucosa of the stomach. Here they produce eosinophilic granulomatous tumors with edema, thickening, and induration which may be mistaken for gastric canceer. The pathalogic changes are thought to be the result of a hypersensitivity reaction. We report a case of chronic gastric anisakiasis, which was diagnosed as submucosal tumor with massive bleeding.

We have experienced 3 cases of recurrent urinary tract infection with ureterovesical reflux under age of 10 years. Two of these patients have completely recovered after surgical reimplantantation which were confirmed by follow-up VCUG 6 to 8 month after surgery. One showed hydronephrotic change of right kidney by intravenous pyelogram taken 7 months after surgical reimplantation. A brief review of the related literature wag also presented and discussed the importance of radiological investigation in recurrent urinary tract infection.

BACKGROUND: Intrathecal injection of analgesic agents sush as opioids, clonidine, ketamine and nalbuphine with a local anesthetic agent during spinal anesthesia for operation is an easy and convenient way to get postoperative analgesia. Intrathecal neostigmine causes an increased ACh concentration in CSF and also has an analgesic effect. This study was designed to examine its postoperative analgesic effect and adverse effects such as nausea/vomiting and urinary retention etc. METHODS: We divided 27 patients who were supposed to receive orthopedic surgery of lower extremities into 3 groups. The control group as injected with heavy bupivacaine 13 mg and normal saline and the N50 and N75 groups were injected with the same amount of bupivacaine combined with neostigmine 50 mcg and 75 mcg respectively. We examined total amount of fluid intake and side effects during operation, and time to first rescue analgesic medication, time to first urination, total applications of rescue analgesic agent, total number of urinary catheterizations for 24 hr after intrathecal injection, and adverse effects of intrathecal neostigmine in the ward. RESULTS: The N75 group showed a significantly longer analgesic duration compared with the control and N50 groups, but the incidence of urinary retention and number of urinary catheterizations increased in the N75 group significantly. Nausea/Vomiting significantly increased in N75 compared with control. Shivering was more common in N50. 2 patients who recieved neostigmine 75 mcg complained of chest discomforts suggesting myocardial ischemia in EKG taken in those episodes. CONCLUSIONS: Neostigmine 75 mcg has better analgesic effect but more frequent adverse effects than control or neostigmine 50 mcg. Therefore, we suggest using high doses of neostigmine cautiously and being aware of its side effects.

A retrospective study was conducted to evaluate the clinical outcomes of midtrimester emergency cervical cerclage in patients with painless cervical dilatation with/without prolapsed amniotic sac, including cases of no previous history of cervical incompetence. 10 patients including 1 twin pregnancy were teviewed for study, All had received emergency cervical cerclage with Macdonald operation or Shirodka operation at 18 to 31 weeksgestation. The procedures were carried out without serious complication except for one patient who had received re-operation 3 days after Macdonald operation because of re-protrusion of amniotic sae. The mean procedure to delivery internal was 8.9+/-5.3 (range 1 to 17) weeks. The mean gestational age at delivery was 32.4+/-5.6 (range 22 to 39+6) weeks for the entire group, 36.1+/-2.6 (range 32+4 to 39+6) weeks for the 6 who achived viability, and 27.6+/-5.0 (range 22 to 29+4) weeks for the 3 who died during the neonatal period. 1 died during gestation and was delivered at 33+6 weeksgestation. The mean birthweight was 2181.6+/-971.6 (range 498 to 3500)g for the entire group, and 2712.9+/- 571.5 (range 1860 to 3500)g for the 7 infants who lived until after neonatal period. The total survival rate for 11 babies was 64%. This study demonstrates that midtrimester emergency cervical cerclage for the patients who have dilated cervix with/without prolapsed amniotic sac is valuable method to try in the cases predicted they would lost the baby with conservative treatment only.

Because central venous O2 saturation (superior vena cava, ScvO2) can be monitored with less risk of the patients than mixed venous O2 saturation (pulmonary artery, SvO2), there have been studies to see if ScvO2 could replace SvO2. But previous studies showed that these two measurements were correlated but "not interchangeable. Therefore the authors compared right atrial C#b saturation (SraO2) with S vO2 over a wide range of cardiorespiratory status including control, hemorrhage, resuscitation, and hypoxia in anesthetized cats. We performed thoracotomy and inserted cannulae directly into the right atrium and the pulmonary artery. Blood sampling were obtained synchronously through the cannulae and tested immediately. The correlation coefficients in control, hemorrhage, resuscitation, and hypoxia groups were 0.876, 0.794, 0.946, 0.948 respectively and the two measurements in each group showed statistically significant correlations (p<0.05). But the biases of the two measurements in each group were 0.11+/-2.9, 0.35+/-4.2, -0.55+/-3.2, 0.23+/-4.2 respectively and the limits of agreement ( 2 standard deviation) in all groups exceeded permissible (5%) to conclude that the two measurements were in agreement. Thus, we reached the conclusion that the absolute values of SraO2, though not being sufficiently identical to S vO2 to calculate O2 uptake or pulmonary shunt precisely, can reflect the S vO2 trend following the O2 supply / demand change. Further clinical studies are needed.
