[EX Q]: Abstract: Purified porcine relaxin (3000 U/mg) was administered im (RLX-IM; 1 mg; n = 2) and in the cervical os (RLX-OS; 1 mg; n = 2) on day 273 (approximately 10 days before parturition normally occurs) of gestation to determine the profiles of immunoreactive relaxin and its effects on progesterone, estrone (E1), and 17 beta-estradiol (17 beta-E2) secretion in peripheral blood plasma of beef heifers. Controls received either 0.01 M PBS (1 ml, im; n = 2) or 0.01 M gel-PBS (gel; 1 ml, os; n = 2) in cervical os. One relaxin-treated (im) heifer calved at 4 h and 36 min after treatment; thus, data from this heifer were not included in subsequent analysis. Relaxin-treated heifers showed an acute elevation in relaxin, a precipitous decrease in progesterone, and a significant (P less than 0.05) elevation of E1 and 17 beta-E2. Plasma relaxin levels were 4.95, 1.5, and 0.24 ng/ml at 0.5 h in RLX-IM, RLX-OS, and control animals, respectively. Peripheral plasma relaxin peaked between 23-31 ng/ml 1-2.5 h before returning to less than 0.5 ng/ml 5-12 h after treatment. Relaxin administration accounted for 70%, 73%, and 58% of the progesterone, E1, and 17 beta-E2 variability between treatments, respectively. An abrupt decrease (P less than 0.01) in progesterone preceded the rises (P less than 0.05) in E1 and 17 beta-E2 at 1.5, 2-2.5, and 2-3.5 h, respectively. Maximum progesterone deviations from the pretreatment mean concentration were -5.43, -3.05, and -0.92 ng/ml for RLX-IM, RLX-OS, and controls. Progesterone rebounded from 36% to 61% and 62% to 79% of respective pretreatment means for RLX-IM and RLX-OS. Peak elevation of E1 was 407.3, 306.5, and 71.5 pg/ml and that of 17 beta-E2 was 82.2, 35.8, and 7.8 ng/ml for RLX-IM, RLX-OS, and controls, respectively. These results provide strong evidence that a pharmacological dosage of relaxin induces an acute depression of progesterone secretion beginning within 90 min in beef heifers during late pregnancy. We suggest that these early and marked luteolytic effects of relaxin on progesterone secretion in cattle could be by direct or indirect actions via mechanisms that are yet unknown.

[EX Q]: Abstract: A series of monoclonal antibodies (mAb) was raised in mice against Schistosoma mansoni, which recognized a carbohydrate determinant on a major Mr greater than 200,000 schistosomulum surface antigen. These mAb cross-reacted with the surface of cercariae and miracidia and with schistosomula of S. haematobium and S. bovis. Other mAb were generated that only recognized a Mr 20,000 schistosomulum surface antigen; they did not cross-react with eggs or miracidia and were species specific. The anti-Mr 20,000 mAb of the IgG1 isotype exhibited high levels of complement-dependent cytotoxicity to schistosomula in vitro. IgM mAb that recognized carbohydrate epitopes of the Mr greater than 200,000 surface antigen blocked the lethal activity of the anti-Mr 20,000 mAb. The IgM anti-Mr greater than 200,000 mAb also reduced complement-dependent cytotoxicity of serum from mice vaccinated with irradiated cercariae.

[EX Q]: Abstract: This case illustrates that massive tumor size, ulceration, or history of multiple recurrences are not absolute prerequisites for metastatic BCC. It supports the hypothesis that tumor proximity to major lymphatic systems or large-caliber blood vessels may be of significance. BCCs originating in skin overlying the parotid gland have the potential to penetrate to a rich vascular and lymphatic plexus as well as compromise the integrity of the facial nerve. Early treatment of these neoplasms utilizing accurate methods of microscopic control appears warranted to prevent the serious consequences of recurrences and deep tissue involvement.
