No full textObservations on the in vitro encystment of Acanthoparyphium spin- losum cercariae revealed that this larval trematode can not be induced to encyst chemically in either 1% glucose or 1% casein hydrolysate. The metacercaria of A. spinulosum will excyst after pretreatment in acidified pepsin for 1 hr, the reductant (sodium diothionite) for 10 min, and then incubation in medium that contained either trypsin and bile salts, or bile salts alone, at 42 C and pH 7.8. Histochemical methods for hydrolytic enzymes (acid and alkaline phosphatase, adenosine triphosphatase, B-glucoronidase, leucine amino- peptidase, nonspecific esterase, acetylcholinesterase, butyrylcholinesterase, chymotrypsin-like protease, o-galactosidase, and 3-galactosi- dase) were applied to the whole mounts of cryostat sections of encysted cercaria, metacercaria, and whole mounts of excysted metacercaria. Reactions for alkaline phosphatase and adenosine triphosphatase occurred throughout the excretory system, including the excretory concretions, while acid phosphatase occurred in the digestive system, oral sucker, and the acetabulum. Reactions for nonspecific esterase and cholinesterase were found throughout the nervous system, the oral sucker and the acetabulum. Nonspecific esterase was observed in the gut of the excysted metacercaria and this reaction persisted after inclusion of 10~4 M eserine in the incubation medium. Including specific inhibitors or activators in the incubation medium after preincubation in 10~5 M diethyl p-nitrophenyl phosphate (E-600) suggested that A- and C- type esterases are present in the gut of the excysted metacercaria. Inclusion of 10'4 M eserine in the incubation medium abolished cholinesterase activity in the nervous system. Histochemical methods for oxidative enzymes were applied to the whole mounts of cercaria, cryostat sections of metacercaria, and whole mounts of excysted metacercaria of A. spinulosum. Positive activity was demonstrated for 6-phosphogluconate dehydrogenase, glucose-6- phosphate dehydrogenase, a-glycerophosphate dehydrogenase, lactate dehydrogenase, succinate dehydrogenase, malate dehydrogenase, isocitrate dehydrogenase, glutamate dehydrogenase, NADH diaphorase, NADPH dia- phorase, and cytochrome oxidase in the cercaria, encysted metacercaria and excysted metacercaria. No activity for alcohol dehydrogenase and g-hydroxybutyrate dehydrogenase was observed in the cercaria, encysted metacercaria and excysted metacercaria. In general, the reactions for both the hydrolytic and oxidative enzymes were more intense in the cercaria than in the metacercaria, suggesting that the cercaria requires more energy than the metacer- caria. There were some hydrolytic and oxidative enzymes that increased in activity within the chemically excysted metacercaria, suggesting that some of these enzymes may aid the worm during excystment and establishment in the final host
The politics of powerlessness: the impact of sex, race, and class on the political and economic development of black women in Hinds County and Sunflower County, Mississippi, 1984
Get PDFIn recent years there have been many studies which have focused on the plight of Black women in the United States. Some of these studies have focused on the issues of racism and sexism and have sought to debunk the myths and distorted pejorative images of Black women. Although the race/sex dichotomy has been investigated, few works have addressed the class question or connected it to race and sex. Even fewer studies have examined race, sex and class as contributors to the political and economic powerlessness of Black women. To achieve a better understanding of the dynamics of race, sex and class and their impact on political and economic development, it was hypothesized in this study that (1) race is viewed by Black women as the primary factor contributing to economic and political powerlessness; (2) sex and class are acknowledged as problems but not as important a force as race; and (3) problems stemming from the issues of race, sex and class will only be addressed on a superficial level within the framework of the American capitalist and patriarchal order. The focus of this study was on Black women in an urban setting (Hinds County) and a rural setting (Sunflower County) in Mississippi. Data were derived from (1) content analysis of books, periodicals, newspapers, videotapes, and manuscript collections; (2) the administration of a survey; and (3) personal interviews with Black women in the two counties. The data supported the basic premises of the study; that is, that race is viewed as the primary problem affecting the economic and political development of Black women while sex and class are of secondary import. Politically, Black women remain a negligible and unorganized force in Hinds and Sunflower Counties. Their political activities have been confined primarily to voting. Economically, they are overwhelmingly in the working/lower class and continue to be channeled into service and domestic occupations. Race, sex and class have been manipulated by those in the American capitalist and patriarchal order who wield power and influence (Whites and males) in order to maintain dominance over Blacks and women. Black women exist in both of these dominated groups; hence, they suffer from dual oppression. Their burden is tripled because of class distinctions. Thus, Black women find themselves at the bottom of the hierarchy in American society. As shown in Hinds and Sunflower Counties, integrating Black women into the American political and economic infrastructure without addressing the problems inherent in that structure has not ended their oppression or exploitation. Reasons for their continued subjugation are clearly connected to the issues of race, sex and class as they operate in capitalist patriarchy
Revitalizing inner cities, auburn avenue with the neighborhood planning unit-m as a mechanism to involve residents, 1987
Get PDFThe major findings of this study are based on the responses to a questionnaire administered to a non-random sample of Neighborhood Planning Unit members from the Auburn Avenue area of Atlanta. Other aspects of the research include additional interviews and an extensive review of the literature. This study attempted to answer three research hypotheses. 1. People who own their homes are more likely to participate more actively in neighborhood meetings than those who do not. 2. People who reside in neighborhoods for five years or more tend to more actively participate in Neighborhood Planning Unit meetings than people who live less than five years in a neighborhood. 3. People of low educational levels tend to participate less than people of higher educational levels. The findings are reflected as follows: (1) Respondents who own their homes did not attend meetings at a higher level than non-owners and (2) Respondents who lived in the neighborhood for more than five years attended meetings more often than those who did not (3) Residents of higher educational levels did not attend meetings more often than residents of low educational levels. In addition, responses to the questionnaire and the other research supported the viability of including residents in the planning process
