BACKGROUND: It had been well known that breast feeding to infants has many advantages and benefits comparing to formula feeding. So, We performed this study to clarify the relationship between immunoglobulin (Ig) levels and diet during newborn period. METHODS: We measured the levels of IgG, IgA and IgM by Array 360 System (Beckman Instruments, CA, U.S.A). Subjects were 29 breast-fed and 13 formula-fed newborns. We evaluated the results and analyzed the change of concentrations of IgG, IgA and IgM according to diet, sex and postnatal period. RESULTS: The levels of IgG, IgA and IgM in breast-fed newborns at postnatal 1-day were higher than formula-fed newborns, but the levels of Ig G and Ig A in formula-fed newborns at postnatal 30-day were higher than breast-fed newborns. CONCLUSIONS: There was no clinical signficance in the difference of IgG, IgA and IgM levels according to diet, sex and postnatal period, respectively.

Malaria is a protozoan disease transmitted by the bite of infected mosquitoes. During acute and chronic malarial infection, altered splenic structure and function produce asymptomatic enlargement or com plications such as hematoma formation, rupture, hypersplenism, or cyst formation. Spontaneous splenic rupture occurs during acute infection, usually during the primary attack. However, rupture occurring in chronic malarial splenomegaly is seldom spontaneous; obvious trauma is almost always the precipitating event. Recently, conservative therapy has been applied in all cases of malarial splenic rupture. Surgical therapy should be reserved for patients with severe rupture or for those with continued or recurrent bleeding. We report the case of a recently treated 25-year-old male who had acute malaria complicated by fever and by severe abdominal pain, tenderness, and distension, a condition that may result in splenic rupture. At operation, the spleen was slightly enlarged and multiple tearing was found in the lateral surface of the capsule. A splenectomy was preformed.

Although Toxocara canis is known to cross the blood-brain barrier, central nervous system involvement is uncommon. Clinical manifestations vary and include cerebral infarction, meningoencephalitis, myelitis, vasculitis or seizure. However cerebral infarction and meningoencephalitis rarely occur simultaneously. We report a case of multiple cerebral infarction combined with eosinophilic meningoencephalitis in a patient with neurotoxocariasis. After control of increased intracranial pressure and treatment with albendazole and steroid, the patient’s clinical symptoms improved markedly.

Organ transplantation has become a' widely accepted treatment modality for end-stage organ disease. The shortage of allogenic donors for organ transplantation has brought about the necessity of xenotransplantation as an unlimited source of organ donation. However, organ transplantation between different species have never been successful because of hyperacute rejection. Although the mechanism of this phenomenon is not fully understood, many researchers believe that the natural antibodies present in the recipient's serum may bind to the graft and induce the activation of complement cascade triggering the process of hyperacute rejection. ...continue...

BACKGROUND: Calcium plays a key role in vascular contraction and regulates receptor sensitivity to certain neurotransmitters. Calcium channel blockers are useful in the treatment of both clinical and experimental hypertension. The present study was designed to examine whether there is an alteration of the activity of calcium channels in association with the development of hypertension. METHODS: Deoxycorticosterone acetate(DOCA)-salt hypertension was made by subcutaneous implantation of DOCA(200mg/kg)strip plus saline drinking(1%) and 2-kidney, 1 clip(2KIC)hypertension by clipping the left renal artery with a silver clip(internal gap of 0.2mm). They were used 4 weeks later. Age-matched normal rats served as a control. Mean arterial pressure(MAP) and heart rate(HR) were continuously recorded from the right femoral artery. The drugs were administered intravenously. RESULTS: Vehicle alone was without effect on MAP or HR. In normotensive rats, nifedipine infusion(5 and 10ug/kg/min)caused a dose-dependent decrease in MAP without significant changes in HR, while Bay k 8644(Bay K, 5 and 10 ug/kg/min) increased MAP transiently. Both the depressor response to nifedipine and the pressor response to Bay k were more marked in DOCA-salt hypetensive rats than in normotensive rats. The maximal changes in MAP indced by nifedipine(5 and 50 ug/kg) or Bay K(5 and 50 ug/kg) were also enhanced in 2KIC hypertensive rats as compared with control rats. CONCLUSION: These results indicate that calcium channel inhibitors and activators can affect on the regulation of blood pressure in an opposite fashion. It is also suggested that the activity of calcium channels might be altered in the developement of experimental hypertension.

Tyrosine kinases have been implicated in vascular smooth muscle cell proliferation and contraction. The involvement of tyrosine kinases in 5-hydroxytryptamine (5-HT)-induced contractile response of the isolated aorta was examined in two-kidney, one clip (2K1C) hypertensive rats, 2141C hypertension was made by constricting the left renal artery and age-matched control rat received sham treatment. Thoracic aortic rings denuded of endotheliurn were mounted in tissue bath, for measurement of isometric contractile force. The putative tyrosine kinase inhibitor, genistein, shifted concentration-response curves to 5-HT toward the right in control rats The isometric force generation induced by 5-HT was also inhibited by genistein in aortic rings from 2K1C: hypertensivc rats, however genistein did not affect on the high concentration of 5-HT in hypertensive rat ;. Genistein-induced relaxations were more attenuated in aortae from hypertensive rats than those from control Genistein had no effect on contrartcion elicited by the direct protein kinase C activator, phorbol 12, 13 dibutyrate (PDBu) either in 2KlC hypertensive or in control Group. These findings indicate that genistein-sensitive tyrosine kinases paeticipate in 5-HT-induced contraction of rat aortic smooth muscle, of which role is apparent in 2K1C: hypertension.

A sarcomatoid carcinoma of the gastrointestinal tract is a very rare tumor. Only limited cases have been reported in the literature. The tumor is more malignant than the usual adenocarcinoma of the gastrointestinal tract. Typically, when discovered, a sarcomatoid carcinoma of the small intestine is already in a late stage of disease with a rapidly progressive course. The survival rate is markedly lower than for adenocarcinomas. Here, we report the case of a 63-year-old male patient who was referred from the Gastroenterology Department of Chonnam University Hospital. He had been suffering from a sudden onset of painless jaundice, and from weight loss for one month. The operation at our hospital was performed under a diagnosis of periampullary cancer. Whipple's operation was carried out on Dec. 14, 1998. Pathology confirmed the diagnosis of a sarcomatoid carcinoma of the duodenum. This article presents that case of a sarcomatoid carcinoma of the duodenum with a brief review of the literature.
