A GIANT INTRAOCULAR FOREIGN BODY OF NONMAGNETIC METAL REPORT OF A CASE

A perusal of the medical literature re- vealod only one case of giant nonmetallic in traocular foreign body, 15x11x7 mm, removed in China However, no mention was made of the operative result of the wounded eye in the report. Usually after removal of intraocular foriegn bodies, especially the giant ones, the eyeball becomes inevitably atrophied, thus it has to be enucleated soon after operation. We removed a giant intraocular metallic foreign body, measuring 18.1x9x1.5 mm and weighing 0.24 g, from the left eye of a patient at our clinic. Follow-up l year after operation found that the eyeball of the affected eye was good in appearance with preservation of partial vision.     

The effect of a carbon dioxide pneumoperitoneum on rabbit follicular oocytes and early embryonic development

The effect of a carbon dioxide (CO2) pneumoperitoneum and its duration on rabbit follicular oocytes was assessed by evaluating fertilization and subsequent embryonic development rates. CO2 may cross the plasma membrane and form carbonic acid, which liberates H+, thus lowering the intracellular pH. There were no significant differences in arterial pH and [HCO3-] between CO2 and air treatment groups, whereas arterial pCO2 and pO2 were significantly increased in the CO2 treatment group. We found that the duration of pneumoperitoneum, irrespective of type of gas used, was negatively correlated with success of embryonic development. These findings necessitate that more attention be given to the gas used for creation of a pneumoperitoneum during egg retrieval for in vitro fertilization and an attempt be made to minimize duration of the pneumoperitoneum.     

Acute post-streptococcal glomerulonephritis followed shortly by acute rheumatic fever

A 16 year old girl with post-streptococcal glomerulonephritis developed acute rheumatic fever 19 days afterwards. Previous publications on concurrent post-streptococcal glomerulonephritis and acute rheumatic fever are reviewed.     

High-dose VP-16 with intermediate-dose cytosine arabinoside in the treatment of relapsed acute nonlymphocytic leukemia

Summary In a study of 11 adult patients with acute nonlymphocytic leukemia (ANLL), infusion therapy with high-dose VP-16 and intermediate-dose cytosine arabinoside was administered. Response was assessed with reference to bone marrow aspirations performed on days 1; 12, 13, or 14; and 21 of treatment. All 7 of the patients with ANLL in relapse achieved marrow hypoplasia, and 3 of them achieved complete response. LFTs were elevated in most patients but no evidence of hepatocellular necrosis was observed. It is concluded that the value of VP-16 in ANLL may have been underestimated in the past because of inadequate dosing.Abbreviations ANLL acute nonlymphocytic leukemia - CGL chronic granulocytic leukemia - DNR daunorubicin - VNC vincristine - ID Ara-C, intermediate-dose Ara-C (500 mg/m² for 12 doses) - HD Ara-C, high-dose Ara-C (3 g/m² for 12 doses) - SGGT serum glutamic transaminase - LDH lactic dehydrogenase - SGOT serum glutamic oxaloacetic transaminase     

Responses of resistance and capacitance vessels in human nasal mucosa to beta-receptor agonists

To investigate the responses of nasal vessels, divided into resistance and capacitance vessels, to a beta-receptor agonist in human, mucosal blood flow of the inferior turbinate and nasal airway resistance were measured when 1.5 mg terbutaline was applied topically. Mucosal blood flow was measured by the hydrogen clearance method just beneath the site where terbutaline in physiological saline (0.02 ml) was applied on an extremely localized area of the nasal mucosa. Nasal airway resistance of the ipsilateral and contralateral nasal cavities was measured separately by anterior rhinomanometry when terbutaline in normal saline (0.1 ml) was sprayed in the unilateral nasal cavity. Topical application of terbutaline elicited neither a significant increase of mucosal blood flow of the inferior turbinate nor an increase of nasal airway resistance. beta-Receptors seem not to be as densely distributed both in the resistance vessels and in the capacitance vessels as to cause vasodilatation by their activation in the nasal mucosa.
