The Distribution Of Macrobenthos In Barataria Basin, Louisiana, Antonio Liborio Philomena

LSU Historical Dissertations and Theses

Macrobenthos and environmental variables were measured in the Barataria basin, Louisiana, at 32 stations in November 1978. Three of the stations (Lake Salvador, Little Lake and St. Denis Bayou) were sampled bimonthly from November 1977 through November 1978. Abundance, diversity, and biomass results indicated two different areas: fresh, low-salinity habitats in the upper and middle basin with high biomass, abundance, and diversity, and high-salinity habitats in the lower basin with low biomass, abundance, and diversity. Over the whole basin, crustaceans were the most abundant organisms, while the mollusks dominated the biomass. Insects, nematodes, and oligochaetes were characteristic of freshwater habitats, …

Nitrification At The Rice Root., Chayong Nammuang Jan 1983

Nitrification At The Rice Root., Chayong Nammuang

LSU Historical Dissertations and Theses

Nitrification at the rice root was investigated. Nitrifiers were found in the rice rhizoplane, rhizosphere and non-rhizosphere soils under flooded conditions. They were greater in the rhizoplane than in the rhizosphere soil and greatest at the heading stage of rice growth. Ammonium-sulfate or NaNO(,2) injected into the flooded soils with growing rice plants did not increase the activities of nitrifiers in the rice rhizoplane. Incubation of the flooded soil with (NH(,4))(,2)SO(,4) or NaNO(,2) did not increase the activities of NH(,4)('+)- or NO(,2)('-)-oxidizers in soils without rice. The (NH(,4))(,2)SO(,4) did not increase denitrifiers, but incubation with NaNO(,2) caused an early increase …

Survival Of Vibrio Cholerae, Biotype E1 Tor, Serotype Inaba In Seafoods., Arthur Hinton Jr

LSU Historical Dissertations and Theses

The D values of Vibrio cholerae in oyster and shrimp meat homogenate were determined at 49(DEGREES), 54(DEGREES), 60(DEGREES), 66(DEGREES), 71(DEGREES), 77(DEGREES), and 82(DEGREES)C. In oyster homogenates, the D values in minutes were 4.7 at 49(DEGREES)C, < 0.35 at 54(DEGREES)C, < 0.35 at 60(DEGREES)C, < 0.33 at 66(DEGREES)C, < 0.30 at 71(DEGREES)C, < 0.29 at 77(DEGREES)C, and < 0.24 at 82(DEGREES)C. In shrimp homogenates, the D values in minutes were 9.17 at 49(DEGREES)C, < 0.43 at 54(DEGREES)C, < 0.39 at 60(DEGREES)C, < 0.32 at 66(DEGREES)C, < 0.31 at 71(DEGREES)C, < 0.30 at 77(DEGREES), and < 0.28 at 82(DEGREES)C. Whole oysters, inoculated with 10('6) V. cholerae/gram, were cooked in boiling water (100(DEGREES)C) or in hot oil (191(DEGREES)C) for one minute. Whole shrimp, inoculated with 10('6) V. cholerae were cooked in boiling water (100(DEGREES)C) or in steam (100(DEGREES)C) for 10 minutes. Vibrio cholerae was not isolated from the cooked oysters or shrimp. Sterile and unsterile shrimp, oyster, crab, and crayfish meat homogenates were inoculated with 10('7) V. cholerae/g. The homogenates were treated with 0, 25, 50, or 100 krad and stored at 4(DEGREES), 0(DEGREES), or -8(DEGREES)C for 21 days. No V. cholerae were isolated from any of the homogenates treated with 100 krad. Vibrio cholerae was able to survive longer in the sterile oyster, crab and crayfish homogenates stored at 4(DEGREES) and 0(DEGREES)C than in the unsterile homogenates stored at the same temperatures. The organism was able to survive longer in the unsterile shrimp homogenates stored at 4(DEGREES) and 0(DEGREES)C than in the sterile homogenates stored at the same temperature. At -8(DEGREES)C, survival time was usually longer in the unsterile seafood homogenates than in the sterile seafood homogenates stored at -8(DEGREES)C. Due to the retardation of competitive inhibition the organism was usually able to survive longer in the unsterile homogenates stored at -8(DEGREES)C than in the unsterile homogenates stored at 4(DEGREES) or 0(DEGREES)C.

The Effect Of Zinc Nutriture On Prostaglandin Synthesis And Fatty Acid Composition In Rat Testes., Prithiva Chanmugam Jan 1983

The Effect Of Zinc Nutriture On Prostaglandin Synthesis And Fatty Acid Composition In Rat Testes., Prithiva Chanmugam

LSU Historical Dissertations and Theses

To determine if zinc affects prostaglandin synthesis in the rat testis, one group of rats was fed a zinc deficient (< 1 ppm) diet and two control groups were pair fed and ad lib fed a zinc sufficient (100 ppm) diet. The diets of half the zinc deficient and pair fed rats were supplemented with docosapentaenoic acid to determine if low levels of this acid, observed in the testes of zinc deficient rats, was responsible for some of the symptoms of zinc deficiency in the testis. In the tunica, 6-keto-PGF(,1(alpha)) and PGE(,2) levels (ng/gm) were lower in zinc deficient rats compared to controls, but there was no difference when PG concentration was expressed as ng/mg protein. In the testis parenchyma, zinc deficient rats had higher levels of PGs, probably due to increased levels of the precursor, arachidonic acid. PG synthesis was greater in tunica compared to parenchyma and in both tissues 6-keto-PGF(,1(alpha)) levels were much higher than those of PGE(,2). Decosapentaenoic acid supplementation had no effect on testis weight, PGs or sperm counts. It also had no effect on 22:5(omega)6 concentration in testes lipids implying that the level of supplementation was too low to have an effect, if any, on the testes. It was concluded that zinc affects PG levels in the testes, but only indirectly, through an effect on protein and fatty acid levels. It was also concluded that PGI(,2) was the major PG produced by the testis and that PG synthesis was an important function of the tunica.

Activity Of Myo-Inositol-1-Phosphate Synthase In The Epididymal Spermatozoa Of Rams., M. W. Loewus, R. W. Wright, K. R. Bondioli, D. L. Bedgar, A. Karl

Faculty Publications

Studies of six 8-9-month-old rams showed that the specific activities of myoinositol-1-phosphate synthase (EC 5.5.1.4) were highest in epididymal spermatozoa, intermediate in testis and lowest in epididymal tissue. The activity per spermatozoon decreased from caput to cauda. The levels of activity of myo-inositol-1-phosphate synthase in ejaculated spermatozoa from four 3-year-old rams and the seminal vesicles of two 3-year-old rams were insignificant, but in pooled Sertoli cells from the testes of young lambs, the specific activity was much lower than in epididymal spermatozoa although activity per cell was of the same order of magnitude. We conclude that epididymal spermatozoa contain a …

Is The Period Of Rapidly Declining Adult Mortality In The United States Coming To And End?, R. Cooper, R. Cohen, A. Amiry Jan 1983

Is The Period Of Rapidly Declining Adult Mortality In The United States Coming To And End?, R. Cooper, R. Cohen, A. Amiry

Faculty Publications

Age-standardized death rates from all causes for persons age 35-74 fell 23 per cent, 1968-1979. The monotonic decline was interrupted by only one period of excess influenza mortality. In the late 1970s, however, the decline in mortality decelerated and no further decrease was observed, 1979-1981. The recurrence of epidemic influenza contributed significantly to this trend although it would appear that the underlying mortality pattern has begun to change.

Bioavailability Of Iron In Beef And Beef-Soybean Mixtures., Felipe Diez Jan 1983

Bioavailability Of Iron In Beef And Beef-Soybean Mixtures., Felipe Diez

LSU Historical Dissertations and Theses

In-vivo and in-vitro studies were conducted to measure bioavailability of iron from beef and beef-soy mixtures. The effects of cooking temperature and method of cooking were investigated. Animals absorbed non-heme iron better than heme forms and utilized iron contained in beef-soy diets as efficiently as that contained in beef diets. Colorimetric iron values of 17.18, 6.0, and 9.02% were obtained in raw, broiled and microwaved beef samples, respectively. A similar trend was observed in beef-soy mixtures when analyzed raw (11.03), broiled (6.32) or microwaved (2.21). Iron contained in beef-soy flour mixtures was dialyzed in a larger proportion (16.60%) as compared …

Recent Trends In Coronary Risk Factors In The Ussr, R. Cooper, A. Schatzkin Jan 1982

Recent Trends In Coronary Risk Factors In The Ussr, R. Cooper, A. Schatzkin

Faculty Publications

The Soviet Union has experienced an increase in the incidence of coronary heart disease over the last 15 years sufficient to result in an overall deterioration in the health of adults. The distribution of coronary risk factors, and the secular trends in diet and cigarette consumption provide a potential explanation for the upsurge in death rates. The animal fat content of the Soviet diet has been steadily enriched since the 1950s and cigarette production increased 72 per cent from 1959 to 1980. The post-Stalin orientation of the Soviet economy toward a policy of motivating the work force primarily through the …
