The one event on signaling mechanism is the cleavage by adenyl cyclase of ATP into second messenger, cyclic AMP. The other transfer system of inositol metabolism, it is widely recognized that hydrolysis of the minor membrane lipid phosphoinositide bisphosphate (PIP₂) initiated by occupation of certain receptors and catalyzed by phospholipase C, lead to toe generation of the two intracellular messengers, inositol triphosphate (IP₃) and diacylglycerol (DG). IP₃ is converted to inositol tetrakisphosphate (IP₄) by IP₃ kinase. In the present study, it is that purification of calmodulin is used by phenyl-Sepharose CL-4B chromatography, it's molecular weigh, 17,000 in SDS-polyacrylamide gel electrophoresis. In order to observe the affinity between calmodulin (CaM)-Affigel 15 and IP₃ kinase, and isolated IP₃ kinase, was applied in CaM-Affigel with Ca²⁺ equilibrium buffer and EGTA equilibrium buffer. We compared with binding and elution effect of IP₃ kinase in several condition of buffer. In affinity of binding, Ca²⁺ equilibrium buffer was in the most proper condition, and elution, CaM/Ca²⁺buffer (CE 1 10.36, CE2 12.76pM/min/mg of protein) was effected much more than EGTA buffer (E2 1.48, E 2.43pM/min/mg of protein), but CaM/Ca²⁺stimulate the activity of IP₃ kinase. And then, several detergents such as sodium deoxycholate, tween 20, cholic acid, polyethylene glycol, chaps were applied. The 0.2% chaps buffer (E2 23.19, E3 8.05pnM/min/mg of protein) was the most effective in elution of IP3 kinase.

A clinical and histopathological study was performed on ninety-four patients with nephrotic syndrome (91 idiopathic and 3 secondary) who were admitted to Department of Internal Medicine, Yeungnam University Hospital during the period of nine years, from January 1985 to May 1994. The results were as following. 1. the ratio of male to female was 1.76:1. In young age group, minimal change was the most predominant type. In old age group, membranous glomerulonephritis and focal glomerulosclerosis were predominant types. 2.- The primary nephrotic syndromes were 96.8% and secondary nephrotic syndromes were 3.2%. Histopathologic findings of 94 renal biopsy tissue were classified into minimal change (43.6%) mesangial proliferative glomerulonephritis (29.8%), membranous glomerulonephritis (12.8%), Typel membranous proliferative glomerulonephritis (4.3%), focal glomerulosclerosis (3.2%) .and others (6.4%). 3. The response of eighty-six patients treated with steroid showed complete remission in 51.2%, partial remission in 20.9%, steroid dependent in 2.3%, and no effect in 25.6% of cases respectively. The response to steroid therapy was most effective in the patients with minimal change lesion. 4. In the patient with membranous proliferative glomerulonephlitis, long-term angiotensin converting enzyme inhibitor treatment showed less deterioration of renal function.

Kawasaki disease (KD) is an immune-mediated disease which is a leading cause of acquired cardiovascular disease in developed country. Recently, tumor necrosis factor-alpha (TNF-alpha) blocker, infliximab has been considered a promising option for patients with refractory KD. Although chronic use of a TNF-alpha blocker could increase risk of opportunistic infections, a few studies have documented that use of infliximab was safe without serious adverse effects in patients with KD. We observed serious bacterial infection after infliximab treatment in an infant with refractory KD. Our patient was a 5-month-old male infant diagnosed with KD who did not respond to repeated doses of intravenous immunoglobulin. We effectively treated him with a single infusion of infliximab (5 mg/kg), but gram-negative (Acinetobacter lwoffii) septicemia developed after infliximab infusion. Therefore, we report a case of serious septicemia after treatment with infliximab, and suggest considering the risk of severe infection when deciding whether to prescribe infliximab to an infant with refractory KD.

Purpose: The purpose of this study was to analyze retinal capillary parameters using optical coherence tomography angiography (OCTA) of the affected eye and the fellow eye of unilateral normal tension glaucoma (NTG) patients and compare the findings with eyes from a normal control group. Methods: A retrospective cross-sectional study was carried out on patients diagnosed with unilateral NTG (24 affected eyes and 24 fellow eyes each) and normal individuals (29 eyes, the control group). OCTA was used to measure the vascular density (VD) and perfusion density (PD) of the macular area and the peripapillary area. Results: In the superficial capillary plexus, the fellow eye group of unilateral NTG patients showed a decrease in VD of the inner-inferior and PD of the inner-inferior and outer-average peripapillary area, compared with the normal control group (p = 0.008, p < 0.001, and p = 0.001). In the affected NTG eye group, the VD (p = 0.014, p = 0.011, p < 0.001, p < 0.001, and p < 0.001) and PD (p = 0.017, p = 0.023, p < 0.001, p = 0.001, and p < 0.001) of the total, inner-average, inner-inferior, and outer-inferior peripapillary area, and the outer-inferior macular area decreased compared to the fellow eye and normal control group, as well as the VD of the outer-average peripapillary area (p = 0.010). The PD of the outer-average peripapillary area (p = 0.003); the VD (p = 0.041, p = 0.008, p = 0.006) and the PD (p = 0.013, p < 0.001, p = 0.001) of the total, inner-inferior, and outer-average macular area; and the PD of the outer-temporal macular area (p = 0.003) were lower than the normal control group. There was no difference in the VD or PD obtained from the deep capillary plexus of the macular area among the groups. Conclusions It is useful to observe retinal capillary parameters using OCTA for patients with unilateral NTG.

BACKGROUND: This study was designed to examine the interactions between mivacurium and vecuronium when administered during a standardized technique. METHODS: Eighty patients (ASA physical status I or II) were randomly assigned to one of four groups (n=20). Their neuromuscular function was measured in response to ulnar nerve supramaximal square-wave TOF stimulation at 10-sec intervals. After the attainment of a stable baseline neuromuscular response, the patients were randomly assigned to receive a rapid iv bolus of either: (1) 3M group (n=20): mivacurium 0.21 mg/kg. Alone, or (2) 2M1V group (n=20): mivacurium 0.14 mg/kg plus vecuronium 0.05 mg/kg, or (3) 1M2V group (n=20): mivacurium 0.07 mg/kg plus vecuronium 0.10 mg/kg, or (4) 3V group (n=20): vecuronium 0.15 mg/kg alone. The onset time of the neuromuscular block, time of recovery of T1 to 25% and reblock time (the time from the reinjection of vecuronium at the time of recovery of T1 to 25% to the time of recovery of T1 to 25%: T25-25) were measured. The intubating condition was evaluated clinically with a scoring system. RESULTS: The onset of block in the 3M group was 33% slower than in the 3V group. The time durations until 25% recovery in the 2M1V, 1M2V and 3V groups were longer than in the 3M group, and the durations in the 1M2V and 3V groups were longer than in the 2M1V group. The T25-25 reblock times of the 2M1V, 1M2V and 3V groups were prolonged in comparison to that of the 3M group. There was no difference in intubating conditions between any of the groups. CONCLUSIONS: A combination of mivacurium with vecuronium provides rates of onset and duration of block which are more effective than an equivalent dose of mivacuriun alone as an additive reaction.

By recent advance of immunologic techniques, it made possible to measure the immune cells and NK cell activity in peripheral blood of various immune altered eonditions. NK cell activity is related not only to malignancies but also to viral infectiona. The facts that the impairment of cell mediated immunity inducea the herpes zoster infection and frequent association with herpes zoster in the patienta with malignancy promote author to atudy the alteration of immune cells and NK cell activity in peripheral block. So author evaluated irnmune cells and NK cell activity of 18 patients with berpes zoster. The results are as follows; 1. The mean value of T cells, T cells showed significant differences between patients group(58.4-i-6.9%, 33.7-+11.7%) and normal healthy control group (68. 6+ 4. 7yo, 44. 2+-7. 0%) but T,' and B cells showecl no significant between patientagroup(6.9-+2.4%, 12.5+-5.7%) and.controlgroup(7.8-1.5%, 13.9-+2.3g%), statistically. 2. The mean value of NK cell activity in patients with herpes zoster group (62. 9+-ll. 2%) showed no significance cornpaired with the mean value of normal healthy control group(57. 9+-l4. 8%), statiatically.
