There are many reports of ventricular arrhythmias following the injection of epinephrine under general anesthesia with halothane or cyclopropane. Raventos reported that catecholamines given animals during chloroform, cyclopropane or halothane anesthesia have caused ventricular arrhythmias which sometimes developed into ventricular fibrillation. But there are a few reports of atrial arrhythmias in patients under general anesthesia with alone halothane. While it is known that hypercapnia can elicit arrhythmia during halothane anesthesia, Black and coworkers that hypercapnia of 60 to 140mmHg (average 92mmHg) is necessary for the occurrence of arrhythmias during halothane anesthesia. Hellewell and Potts reported 12 cases of arrhythmias under halothane anesthesia which were treated by propranolol, producing a return of sinus rhythm in an average time of 46 seconds. The authors reported one case with atrial arrhythmias induced by halothane anesthesia, which were arrested by the IV injection of 5mg of tolamolo, beta-receptor blocking agent. Thereafter arrhythmias did not reappear.

We studied the serum electrolytes in the 727 normal persons who visited Busan University hosptial, Benedict Hospital and Maryknoll Hospital from 1970 to 1976. The results were as follows: 1. Mean value of the serum Na+ being measured in 729 normal persons was 138.7+/-6.2mEq/L and 140+/-6.5mEq/L in 450 male, while 136.8+/-6.6mEq/L in 279 female. 2. Mean value of serum Cl- being measured in 701 persons was 99.6+/-5.9mEq/L, and 99.7+/-6.0mEq/L in 437 male while 100+/-5.7mEq/L in 264 female. 3. Mean value of serum K+ being measured in 707 normal persons was 4.4+/-0.9mEq/L in 434 male, while 4.2+/-0.8mEq/L in 273 female. 4. Mean value of serum Ca+ being measured in 557 normal persons was 4.5+/-0.6mEq/L and 4.7+/-0.7mEq/l in 355 male, while 4.3+/-0.5mEq/L in 202 female. 5. Mean value of serum phosphorus being measured in 94 normol persons was 4.2+/-0.6mg%, and 4.1+/-1.0mg% in 65 male, while 4.5+/-1.5mg% in 29 female.

Unknown primary melanoma shows only metastatic malignant malanoma without obvious primary tumor. These unusual instances of unknown primary melanoma have reported incidences of 1.0~8.7%. This 51 year old patient had many intra-abdominal and mesenteric masses without visible primary tumor. The most commonly accepted explanation for unknown primary melanoma is spontaneous regression of a primary skin lesion.

This study was carried out to investigate the ultrastructural findings of rats after administration of 0.5% lead acetate with drinking water. The Sprague-Dawley rats were divided into control and experimental groups. The control group was composed of 12 rats and was orally administered with 0.5% sodium acetate. The experimental group was composed of 36 rats and orally administered with 0.5% lead acetate. Two rats in the control group and four rats in the experimental group were sacrificed on day 2, and week 1, 2, 4, 6 and 8 after administration. The kidney was extirpated and examined by electron microscopy. The results obtained were as follows: The blood lead concentration in the experimental group began to increase from the second day after administration and it increased gradually until the 6th week and it decreased at the 8 week. The urinary excretion of delta-ALA also increased from the secondary and gradually increased up to the 8th week. On electron microscopic examination, the proximal tubular cells showed fat droplets, dilatation of the endoplasmic reticulum, mitochondrial swelling, increased numbers of secondary lysosomes and myelin figure-like residual bodies and intranuclear inclusion bodies. All these findings peaked at the eighth week after administration. Ultrastructural findings after Timm sulphide silver reaction revealed the lead granules in the proximal tubular lumen and between the microvilli of the proximal tubular cells without membrane-bounded. It can be concluded that most of the changes of micro-organelles are compatible with degenerative changes of lead exposure and passive diffusion of lead granules are involved in the proximal tubular cells.

The authors investigated the radioallergosorbent test (RAST) for the specific IgE and the prick test with hose dust mite in 129 patients with atopic dermatitis(AD) wit4 four or more family numbers. RAST and prick test results were described according to family background of respiratory atopy(RA) and severity of AD. The results are summarized as follows : l. A comparison between the prick test results and RAST reactions gave a concordance of 88%. The prick test was more sensitive than the RAST. 2. The level of specific IgE in patients with personal history(PH) or family history(FH) of RA was significantly increased compared to those in patients with only AD. 3. In patients without PH and FH of RA, the level of specific IgE in patients with FH of AD was significantly increased compared to those in patients without FH of AD. 4. The level of specific IgE did not reflect the severity of AD. From the above results, it could be concluded that type I allergy to house dust mite is not directly related to AD and it occurs predominantly in those patients with AD wha have a predisposition to RA.

The concurrence of typical carcinoid admixed with adenocarcinoma of the gastrointestinal tract is a well known but unusual phenomenom that has been reported in the esophagus, stomach, gall bladder, colon and appendix. The amine precursor uptake and decarboxylation (APUD) concept included the idea that neuroendocrine cells of the gastrointestinal tract were dervied from the neural crest by a process of migration during embryogenesis. However the intimate admixture of cells which have morphologic and immunocytochemical properties of both carcinoid tumors and adenocarcinoma suggests that these tumors are derived from a multipotential stem cell showing bidirectional differentiation rather than from unrelated cell lines. The term composite carcinoma-carcinoid tumor is therefore an appropriate designation for these neoplasms. We report a case of composite carcinoma-carcinoid tumor of the stomach in a 38 year-old female with brief review of literature.

PURPOSE: To evaluate the usefulness of Gd-DTPA enhanced MR imaging in determining the metastatic lymph nodes in uterine cervical carcinoma. MATERIALS AND METHODS: Sixty nine patients with histologically proven cervical carcinoma underwent Gd-DTPA enhanced MR imaging. One hundred and thirty-eight pelvic regions(69 right,69 left) in 69 patients were analyzed for lymph node metastases. Pelvic lymph nodes were considered to be abnormal if they were greater than lcm in diameter and were enhanced on postcontrast T1 weighted images. RESULTS: Metastatic lymph nodes were found in 22 pelvic regions by surgicopathologic examinations. On MR imaging there were 14 true positives, 106 true negatives, 10 false positives and 8 false negatives. Gd-DTPA enhanced MR image had an accuracy of 86.9%, a sensitivity of 58.3%, a specificity of 91.4%, a positive predictive value of 58.3% and negative predictive value of 92.9% in evaluation of pelvic lymph node metastases. CONCLUSION: MR imaging with contrast enhancement may be useful in the evaluation of pelvic lymph node metastases in patients with uterine cervical carcinoma.

BACKGROUND: Gamma linoleic acid (GLA, Epogam) is considered a safe and effective modality in the treatment of atopic dermatitis (AD) in which impaired function of the enzyme, delta-6-desaturase, has been reported to result in reduced levels of GLA, desaturated fatty acids. OBJECTIVE: We performed this study to observe the changes of skin surface conditions measured objectively by bioengineering methods in relation to clinical improvement after treatment with GLA (Epogam®) in children with AD. METHODS: Thirty-four children with AD were treated with GLA (Epogam®) and evaluated with clinical parameters.The changes of skin surface conditions were monitored by non-invasive experimental instruments. RESULTS: There was a significant decrease of transepidermal water loss (TEWL) and gradual improvements in clinical severity after 12 weeks of GLA (Epogam®) treatment. The change of skin surface pH was statistically significant on the antecubital fossa and abdomen except the popliteal fossa. The other parameters including skin surface hydration and skin surface lipid did not show consistent changes. CONCLUSION: Clinical improvement of AD with GLA (Epogam) seemed to be achieved by the reduction of TEWL.
