Eight patients in the state of ASA classification l, ll were investigate. Blood samples were collected before, just after, 30 minutes after and 60 minutes after induction of anesthesia. Glucose and electrolyte changes in relation to maintenance fluids in balanced and halothane anesthesia were as follows. 1) In both anesthetic techniques blood sugar level showed increasing tendency according to duration of anesthesia. 2) There were no specific changes in serum electrolytes related to type of anesthesia. 3) The administration of D/S and H/D showed a little increase in Na+ and Cl- level compared to the administration of just DsW. 4) The administration of H/d showed less increase in K+ level than the administration of DsW or D/S. 5) Just after induction of anesthesia the K+ level increased a little and decreased gradually thereafter.

Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

The purpose of this study was to investigate the characteristics or the potassium channels existing in the rat urinary bladders. Smooth muscle strips of rat detrusor urinae were examined by isometric myography. Relaxation responses of detrusor muscle strips to the three potassium channel openers pinacidil, a cyanoguanidine derivative, BRL 38227, a benzopyran derivative and RP 52891, a tertrahydrothiopyran derivative were examined. The potassium channel openers reduced the basal tone, and the rank order of potency was RP 52891>pincidil>BRL 38227. Procaine, an inhibitor of the voltage-sensitive potassium channel tended to increase the basal tone, but it did not affect the relaxant effects of the calcium-activated potassium channel opener did not antagonize the relaxant effects, but it reduced the Emax of RP 52891 and BRL 38227. Glibenclamide, an inhibitor of the ATP-sensitive potassium channel, antagonized the relaxant effects of pinacidil, RP 52891 and BRL 38227 reducing the Emax of RP 52891 and BRl 38227. Galanin which inhibits secretion of insulin through opening the ATP-sensitive potassium channels in pancreatic β-cells rather increased the basal tone of the isolated detrusor strips. These results suggest that the urinary bladder of the rat has mainly the ATP-sensitive, glibenclamide sensitive potassium channel, which is a different type from that in the pancreatic β-islet cells.

We investigated the effects of panretinal photocoagulation (PRP)on macular microcirculation in diabetic retinopathy. PRP using argon blue green laser was performed in 23 eyes of 15 patients with early proliferative diabetic etinopathy and very severe nonproliferative diabetic retinopathy without significant macular edema. The changes in volume, flow, velocity of macular microcirculation were measured before PRP, 1 hour, 1 day, 1 week, and 1 month following PRP, using Heidelberg Retina Flowmeter(HRF). Mean volume, flow, velocity of macular microcirculation decreased to a maximal degree 1 hour following PRP, from 14.87+/-0.40, 387.45 +/-101.40, 1.40+/-0.28(before PRP)to 12.44+/-1.39, 347. 33+/-100.39, 1.27+/-0.34(p<0.05). From 1hour to 1 month after PRP, macular microcirculation gradually increased. However, throughout this period, all parameters of macular microcirculation remained lower than pre-PRP level(p<0.05). Our study suggests that panretinal photocoagulation reduces the macular microcirculation in diabetic retinopathy.

The Foster Kennedy syndrome is ipsilateral optic disc atrophy and contralateral optic disc edema that is caused not only frontal lobe tumor but also another intracranial tumors and non tumorous conditions. In this case, suspected neurofibromatosis by the skin and ocular manifestations, there are glioblastoma multiforme in left temporoparietal lobe and undefined mass with bony destruction of the ipsilateral sphenoidal wing ridge. Authors asserted that ipsilateral optic atrophy was caused by direct compression of the undefined mass on sphenoidal wing ridge to the optic nerve and the contralateral disc edema was result from high intracranial pressure caused by glioblastoma multiforme.

This study was performed to investigate the effect of octreotide on the contractility of rat vas deferens. The -smooth muscle strips isolated from the prostatic portion were myographied in isolated organ bath. Electric -field stimulation (monophasic square wave, duration : 1. mSec, voltage : 50 V, frequency : 5 Hz or 30 Hz, train : 10 Sec) produced reproducible contraction. The contraction was composed of two component, first phasic component (FPC) and second tonicc component (STC).. These contractions were abolished by -tetrodotoxin (1 microM). Octreotide inhibited the field stimulation induced contractions both FPC and STC concentration- dependently. The FPC was decreased by a desentization of purinergic receptor by pretreatment of mATP, and the STC was decreased by pr,,creatment of reserpine (3 mg/kg, EP) 24 hours before experiments. Octreotide reduced the field stimulation induced contraction in the presence of mATP and of reserpinized muscle strips. The inhibitory effect of octreotide was more potent at 5 Hz than at 30 Hz. Octreotide did not affect basal ton and exogenous norepinephrine- or ATP-induced contraction. These results suggest that octreotide inhibit the contractility of the isolated rat vas deferens by inhibition of the release of neurotransmitters, both ATP and norepinephrine from adrenergic nerve terminal.
