Relationship between cannabis use and psychiatric disorders in patients admitted at Dr George Mukhari Hospital Psychiatric Unit

Modisane, L. N. January 2010 (has links)
Thesis (M Med (Psychiatry))--University of Limpopo, 2010. / BACKGROUND Cannabis is the commonly used illicit drug of choice in South Africa and throughout the world. The majority of individuals who use cannabis do not report adverse reactions to it, however a minority of heavy users will develop problems. A substantial number of patients admitted at our psychiatry unit seem to be using cannabis. AIMS The aim of the study was to assess the relationship between cannabis use in psychiatric disorders in patients admitted in George Mukhari Hospital Psychiatry Unit, to determine the pattern of cannabis use, to identify the common psychiatric disorders in patients using cannabis, to determine the socio-economic factors that may lead to cannabis use. METHODS A total of 75 participants admitted at Doctor George Mukhari hospital and diagnosed with psychiatric disorders according to the diagnostic and statistical manual of mental disorders fourth edition text revised were interviewed using a structured questionnaire and had urine specimens collected for analysis. Out of 75 participants a control group of 34 participants who tested negative for urinary cannabinoids were interviewed. The participants had signed a written informed consent in their language of preference. The study had been approved by the Research Ethics and Publications Committee of the University of Limpopo (Medunsa Campus).Data was analysed with the help of the statistician and reported on graphs, pie-charts and tables. RESULTS 16(39%) of participants who tested positive were diagnosed with schizophrenia, 7 (17%) of those who tested positive were diagnosed with cannabis induced psychotic disorder, 5(12%) of those tested positive were diagnosed with psychosis due to GMC (HIV) and 6(15%) were diagnosed with psychosis due GMC (epilepsy). 8(24%) of those who tested negative were diagnosed with schizophrenia, 15(44%) of those tested negative were diagnosed with cannabis induced psychotic disorder, 2(6%) were diagnosed with psychosis due to GMC (HIV) and to 2(6%) of those who tested negative were diagnosed with psychosis due to GMC (epilepsy). Majority 24 (32%) smoked cannabis using pipes 4-5 times, 19 (25%) used zols 4-5 times, 12(16%) used pipes 2-3 times, 11(14%) used 1 zol in the 30 days prior to the interview. Most of the participants were of low socio-economic status and had started using cannabis early in their lives. CONCLUSION Cannabis use is related to a number of psychiatric disorders in patients admitted at Dr George Mukhari Hospital. Schizophrenia, cannabis induced psychotic disorder, psychosis due to GMC (HIV), psychosis due to epilepsy were the commonest identified disorders.

Cannibals ate my title : or, Melville's white cannibalism and the laboring body

Schlein, Helene Remy 08 October 2014 (has links)
In Herman Melville’s first novel Typee, he creates a culture of Polynesian cannibals as decidedly more civilized than the comparatively “savage” American missionaries. This report examines Melville’s use of cannibalism as a central metaphor beyond Typee and throughout his works, spanning both time and genre, to complicate U.S. American capitalism and slavery. Melville illustrates how a body’s potential for labor determines its use value to an exploitative extent in which man-eating and laboring become practices that mirror each other and, in conversation, self-destruct. This report traces how Melville expands the object of the cannibal from other to self, ultimately warning that the desires that underlie cannibalism eat at the nation until it consumes itself from the inside, “[feeding] upon the sullen paws of its gloom!” (M-D 131). Melville applies notions of the cannibal from Typee onto the laboring body in Moby-Dick, suggesting cannibalism as tangential to capitalism and wage labor. Melville later revises this association in the short story “Bartleby, the Scrivener,” in which the laborer rejects capitalism and is left to feed on his own body. This preoccupation continues through Benito Cereno, in which slaves cannibalize their master and commandeer the slave ship. While his uses of cannibalism are often shrouded in wordplay and allusion, Melville develops a domestic cannibalism from Moby-Dick’s Ahab’s monomania through Benito Cereno’s Babo’s rage. Melville’s consistent use of cannibalism as a metaphor for self-destrucion adumbrates a career-long tendency to break down differences between the civilized and the savage, ultimately to reveal the United States’ manipulation of laboring bodies as cannibalism disguised. / text

Effects of post-settlement habitat use and biotic interactions on survival of the seagrass-associated fish red drum (Sciaenops ocellatus)

Fencil, Megan Christine 23 August 2010 (has links)
Due to high mortality encountered by marine fish larvae during their first weeks of life, small changes in the number of individuals surviving through this period can cause large fluctuations in year-class strength. Larval Red Drum (Sciaenops ocellatus) are dependent upon structured estuarine habitat to avoid predation. A study of post-settlement larval Red Drum distribution in a subtropical seagrass meadow in Mission-Aransas Estuary, Texas, USA indicates that larvae settle over approximately two months. Abundance of larger settled larvae was significantly different among sites. The areas of highest larval abundance varied temporally, indicating that the entire extent of the seagrass bed is utilized. Regression analysis of abiotic environmental factors did not explain why larvae were more abundant at particular sites. To characterize the structure and variability of the fish species assemblage that Red Drum encounter upon settlement, larvae and juveniles were captured in the seagrass meadow during weekly collections. Of the 32 fish species collected, seven represented 92% of the assemblage. Multivariate species analysis indicated that collections widely separated in time and space shared the lowest Bray-Curtis similarity. Because Red Drum settle over a relatively long period and co-occur at body sizes known to cause cannibalism under laboratory conditions, I tested combinations of small and large Red Drum larvae at various field-realistic densities and at different levels of seagrass habitat structure to determine potential for cannibalism. Artificial seagrass did not protect small (5 – 6 mm SL) larvae from cannibalism, but natural dense seagrass had a protective effect relative to edge habitat. The final component of this research examined the emergent impacts of a common predator pinfish (Lagodon rhomboides) on mortality and cannibalistic interactions between small and large Red Drum larvae. Both pinfish and large Red Drum larvae alone readily consumed small Red Drum in all seagrass habitat structures tested. However, the combined treatment of pinfish and large Red Drum together led to reduced mortality of small Red Drum. Predation can significantly affect Red Drum survival during the post-settlement period, and multiple predators may have a protective effect on the smallest settlers if predation pressure is re-directed towards a larger size class. / text

Srovnání míry kanibalismu u okouna říčního a candáta obecného v prvním roce života / Comparision of rate of pike and pike perch cannibalism in first year of life

SVATEK, Petr January 2013 (has links)
Abstract Larvae of perch (100-200 thousand per ha) were planted into the ponds Bejkovna (1,33 ha) and Kamenný (1,54 ha). Larvea of pikeperch (150 - 300 thousand per ha) into the ponds Hejškův (0,88 ha) and Hadač (2,7 ha). Pond Bagr was used such as an additional data source. The aim of this study was Comparision of rate of pike and pike perch cannibalism in first year of life. There wasn?t observed cannibalism and different sizes of perch individuals in the ponds Bejkovna and Kamenný. Total length (TL) of the fish was 50,5 ? 2,85 mm in the pond Bejkovna and 41,58 ? 1,56 mm in the pond Kamenný at the end of observed period. Average growth rate was 0,86 mm/day in pond Bejkovna and 0,7 mm/day Kamenný. There was also no cannibalism by the perch (TL = 57,2 ? 1,34 mm) from the pond Bagr. It was possible to observe few individuals of roach (Rutilus rutilus) in the digestive tract. The level of cannibalism was 23 % in the pond Hadač and also in the pond Hejškův. The average TL was 31,59 ? 3,89 mm (average growth rate 0,9 mm/day) in the pond Hadač at the beginning of June and 26,83 ? 2,51 mm (average growth rate 0,77 mm/day) in the pond Hejškův. The average TL was 48,7 ? 10,04 mm in the pond Hadač at the end of June. There was observed cannibalism in the pond Hadač at the beginning of the June and also at the end of this month. TL of prey fish was 66,1 and 61,6 % of cannibals TL. There was observed cannibalism in the pond Hejškův until the mid of September. The average TL was 140,6 ? 35,4 mm here and cannibalism was observed in 23 % of cases. TL of prey fish was 54,9 % cannibals TL. The most important thing of the monoculture rearing of perch and pikeperch is sufficient amount of food. This is especially true in the case of pikeperch. Key words: Cannibalism, pike perch, perch

Intraspecific Interference Among Larvae in a Semivoltine Dragonfly Population

Crowley, P. H., Dillon, P. M., Johnson, D. M., Watson, C. N. 01 February 1987 (has links)
This study focuses on ways that the size distribution of individuals influences the types and intensities of competitive interactions within a population of aquatic arthropod predators. Three field experiments and one laboratory experiment were designed to test for feeding interference, interference mortality, and dispersal effects within and between larval size classes of the primarily semivoltine dragonfly Tetragoneuria cynosura in Bays Mountain Lake. One field experiment documented the temporal pattern of colonization of large-mesh cylinders by the small, first-year-class larvae during a 30-day period; the results are consistent with passive (density-independent) colonization. A second field experiment examined the effect of large, second-year-class larvae at densities of 1 or 3 per cylinder (14 or 42 m-2) on colonization by small larvae; this colonization was inhibited at the high density of large larvae. In the laboratory experiment, when larvae of the two size-classes were together in the same aquarium, small larvae moved around less than when by themselves (dispersal inhibition). Thus the inhibition of colonization observed in the field may result from interference mortality, rather than from a flight response to the presence of larger conspecifics. To evaluate this interpretation, the third field experiment measured the in-situ functional response of large larvae to each other and to their small conspecific prey. Results suggest a type 1 (linear) functional response, with feeding inteference among large larvae. Moreover, the interference mortality inflicted by larger larvae on smaller conspecifics was apparently more intense on larger individuals within the small size-class. Taken together, the three field experiments and a statistical power analysis show how colonization and interference interact to determine the local density of small larvae, and why such interference effects are difficult to detect experimentally in the field.
