An Investigation Of The Behavioral Effects Of Methylphenidate Hydrochloride On Schedule-Induced Polydipsia In Rats, Linda Sederquist Smith Jan 1975

An Investigation Of The Behavioral Effects Of Methylphenidate Hydrochloride On Schedule-Induced Polydipsia In Rats, Linda Sederquist Smith

Masters Theses

The influence of methylphenidate hydrochloride injections on six male Charles River rats displaying schedule induced polydipsia was examined in this study. Bar pressing, licking, and water consumption were measured during a total of 63 daily one hour trials conducted with a variable interval 60-second schedule of bar pressing for pellets with water constantly available. The polydipsic response was acquired by subjects during the first 28 trials. Subjects were then divided into experimental and control groups. The experimental subjects recieved a 1 mg/kg injection of methylphenidate prior to regular trials 29-49 and extinction trials 50-63. Control subjects were injected with a …

Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman Jan 1975

Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman

Masters Theses

Ninety channel catfish (Ictalurus punctatus) were trapped during September 1973 through April 1974 at three hatcheries located at Worden, Centralia, and Kinmundy, Illinois. All were examined for parasites and 87 were parasitized. The trematodes Azygia angusticauda and Neascus sp. were found in the gastrointestinal system and Cleidodiscus floridanus and Dactylogyrus sp. were attached to the gills. Five cestode genera, including Bothriocephalus sp., Corallobothrium giganteum, Eubothrium sp., Haplobothrium sp., and Proteocephalus ambloplitis were present. Rhabdochona sp. was the only nematode found. Protozoans; Costia sp., Myxobolus sp., Scyphidia macropodia and Trichodina discoidea and one kind of glochidium were observed. …

The Histology Of The Pineal Gland In Odocoileus Virginianus, Terry Michael De Villiers Jan 1975

The Histology Of The Pineal Gland In Odocoileus Virginianus, Terry Michael De Villiers

Masters Theses

A total of 26 pineal glands from the white-tailed deer were histologically examined. Five different stains were utilized to determine various cell types present in pineal tissue. Connective tissue septa divide the pineal gland into incompletely separated lobules which are supplied by a very extensive vascular system. The pinealocyte is the most numerous cell in the gland and is most easily recognized by a prominent nucleus approximately 6-8 microns in diameter. The pinealocyte cytoplasm contains many minute granules. A distinct difference was noted in the histology of the oldest age deer pineal (age 7 years) when globular granules were observed …

Method Of Karyotype Determination For Cercaria: Application To Family Azygiidae (Trematoda), James Everett Mick Jan 1975

Method Of Karyotype Determination For Cercaria: Application To Family Azygiidae (Trematoda), James Everett Mick

Masters Theses

The development of a method for karyotype determination of cercaria provides a basis for comparative karyotype analysis between cercaria and adult, possibly eliminating the need for infection experiments for positive identification of cercaria. Snails (Goniobasis livescens) were collected from below the spillway of Lake Charleston, on the Embarras River, near Charleston, Illinois. Of a total of 196 snails collected 42 (21.5%) were found to be infected with undetermined furcocyticercous cercariae. Infected snails were detected through isolation procedure. From the infected snails, emerged and non-emerged forms of the cercaria were recovered. Whole mounts of the cercaria were made and …
