An immunological investigation of human pituitary growth hormone     

HAYASHIDA T  LI CH 《Science (New York, N.Y.)》1958,128(3334):1276-1277

Growth hormone isolated from human pituitaries has been demonstrated to be a good antigen in the rabbit. With the rabbit antiserum to human somatotropin, it is possible to detect as little as 0.1 microg of the hormone by precipitin test. The antiserum was also capable of neutralizing the growth-promoting activity of human somatotropin.  相似文献   

Adjuvant effects of sugar cane extracts (SCE) in chickens

The effects of sugar cane extracts (SCE) on immune responses in chickens were studied. Two- or 10-month-old chickens orally administered SCE (500 mg/kg/day), for 3 consecutive days before immunized with sheep red blood cells, Brucella abortus and Salmonella Enteritidis organisms, showed significantly increased and prolonged antibody responses to these antigens, compared to control chickens without SCE. Furthermore, chickens orally administered SCE also revealed enhanced delayed type hypersensitivity responses to human gamma globulin. These results indicated that SCE has immunostimulating and adjuvant effects in chickens.  相似文献   

Challenges to controlling rabies in skunk populations using oral rabies vaccination: A review          下载免费PDF全文

Controlling rabies in skunk populations is an important public health concern in many parts of the United States due to the potential for skunk rabies outbreaks in urban centres and the possible role for skunks in raccoon rabies variant circulation. Oral rabies vaccination (ORV) programmes have supported wildlife rabies control efforts globally but using ORV to control rabies in skunk populations has proven more challenging than with other target species, like foxes, coyotes and raccoons. A review of published studies found that some ORV constructs are immunogenic in skunks and protect against virulent rabies virus challenges, especially when delivered by direct installation into the oral cavity. However, in field ORV programmes using currently available vaccine‐bait formats and distribution methods targeting other rabies reservoir species, skunks often fail to seroconvert. Field effectiveness of ORV in skunks appears to be limited by poor bait uptake or inadequate ingestion of vaccine rather than from poor vaccine efficacy. Observations of captive skunks revealed vaccine spillage when handling and biting into baits such that modification of bait formats might improve field effectiveness. In addition, a dose–response relationship between bait distribution density and post‐baiting seroconversion among skunks was observed across the limited number of field studies. Additional research is needed to identify opportunities to modify ORV baits and distribution strategies to improve the viability of ORV as a rabies control strategy in skunks.  相似文献   

Physiological changes induced by salt intake in female Spontaneously Diabetic Torii‐Leprfa (SDT fatty) rat,a novel obese type 2 diabetic model

Salt plays an important role in the control of blood pressure in obesity and diabetes mellitus. In this study, we investigated physiological changes such as blood pressure and renal function in salt‐loaded female Spontaneously Diabetic Torii‐Lepr^fa (SDT fatty) rats. SDT fatty rats were given 1% NaCl in drinking water for 14 weeks, from 4 to 18 weeks of age. Significant salt‐sensitive hypertension was observed in the salt‐loaded SDT fatty rats. Moreover, the salt‐loaded rats showed a decrease of creatinine clearance and deterioration on pathological renal findings, including glomerulosclerosis and tubular and interstitial lesions. Female SDT fatty rat is a useful model for investigating the mechanisms of high salt sensitivity in obesity and diabetes mellitus.  相似文献

Utility of progesterone receptor-ires-Cre to generate conditional knockout mice for uterine study     

Takafumi Namiki  Maki Kamoshita  Atsuko Kageyama  Jumpei Terakawa  Junya Ito  Naomi Kashiwazaki 《Animal Science Journal》2021,92(1):e13615

In mice, the conditional knockout strategy using the Cre-loxP system is useful for various types of research. The Cre mouse line with progesterone receptor promoter (Pgr^Cre) has been widely used to produce specific uterine gene-deficient mice, but in the Cre line, endogenous Pgr gene is replaced by Cre recombinase gene, which makes the breeding of homozygous mice (Pgr^Cre/Cre) difficult because they are infertile. Yang et al. (2013, https://10.1016/j.cell.2013.04.017 ) reported the generation of another Pgr^iresCre mouse line that still has endogenous Pgr gene, and they inserted Cre recombinase downstream of the Pgr gene via an internal ribosome entry site (IRES). It is possible that this new Pgr^iresCre line would be useful for uterine research as the mice can be bred as homozygotes (Pgr^{iresCre/iresCre}). Herein, we confirmed the Pgr^iresCre mice effectively directed recombination in the female reproductive tract and was capable of genetic alteration in the endometrium that enables the studies of its uterine function. Our findings demonstrate that the new Pgr^iresCre mouse line is also useful for the generation of uterine-specific knockout mice. The findings using Pgr^iresCre mouse will contribute to the understanding of reproductive systems and diseases in humans and domestic animals.  相似文献
