Short And Long Term Effects Of Proton Microbeam Irradiation : In The Lateral Geniculate Nucleus Of Felis Domesticus, Chad Sherwood Reder

Loma Linda University Electronic Theses, Dissertations & Projects

Little is known of the effects of proton irradiation on neural tissue. A 1.0 mm microbeam was used on the cat lateral geniculate nucleus (LGN) to quantify the short term (< 3 months) and long term (< 9 months) effects of radiation damage. The LGN is a large structure with well defined afferent, efferent, and receptive field properties.

Electrophysiological and histological techniques were used to examine the effects of the microbeam at 60, 40, and 16 Gy, administered as a single bolus. Recordings of light evoked responses in the LGN were obtained using microelectrodes in nine animals within 12 weeks of irradiation, and 6 animals within 36 weeks of irradiation. Receptive fields were mapped onto a tangent screen using standard receptive field techniques. Histological measures included afferent …

Stab Wounds To Rat Brains : Demyelination, Remyelination And The Cellular Response, Particularly Of Oligodendrocytes, Xie Dangci

Loma Linda University Electronic Theses, Dissertations & Projects

The present body of knowledge concerning the results of central nervous system injury is incomplete and controversial. The role of oligodendrocytes, the cells involved in phagocytosis, the stages of demyelination, and the evidence for remyelination are of interest. Following stab wounds to rat brain cortex, corpus callosum and hippocampus, the animals were examined at 4,7,11,18,23,29,45,60 and 70 days postoperation (dpo). To help in the identification of cells immunocytochemical markers for astrocytes and immature oligodendrocytes were used. These were labels for glial fibrillary acidic protein (GFAP) and myelin/oligodendrocyte specific protein (MOSP) respectively. Light and electron microscopy were correlated using conventionally prepared …

Laparoscopic Appraisal Of Infertility And Pelvic Pain In Pakistani Women: A 5 Years Audit, R Hamid, K S. Khan, T Mubeen, J A. Razzak

Department of Obstetrics & Gynaecology

Five hundred and nine Laparoscopic examinations performed between 1987-91, (147 procedures for evaluation of gynaecologic pelvic pain and 313 for infertility) revealed ectopic pregnancy (27%), twisted ovarian cyst (18%) and acute pelvic inflammatory disease (14%) in cases of acute gynaecologic pain, and endometriosis (17%) and chronic pelvic inflammatory disease (16%) in chronic pelvic pain. Adhesions (20%), tubal block (15%), endometriosis (9%) and polycystic ovary (7%) were common findings in cases of infertility. These data support the usefulness of this minimally invasive procedure in accurate diagnosis of gynaecological disorders and provides insight into the spectra of diseases seen in Pakistani women …

Complexity Of Fetal Movement Detection Using A Single Doppler Ultrasound Transducer, William A. Russell Jr., Curtis L. Lowery, Patrick J. Baggot, James D. Wilson, Robert Walls, Roger M. Hawk, Pam Murphy

Journal of the Arkansas Academy of Science

The objective of this paper is to discuss the complexity of fetal movement detection encountered during development and implementation of an automated single Doppler ultrasonic transducer based instrument. The single transducer instrument was intended to better quantify the duration, velocity, and magnitude of fetal movements. A Corometrics Model 116 fetal heart rate monitor was modified, and a fetal movement detection algorithm (Russell Algorithm) was developed to detect fetal movements on one and two (data fusion) transducers. A Hewlett-Packard (HP) M-1350-A fetal monitor and the Russell Algorithm were used to detect and record fetal movements concurrently on sixty patients between the …

Section of Haematology/Oncology

Serum levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and trigly cerides (TG) were determined on 239 school children aged 5-19 years belonging to lower middle class families. The mean TC, LDL-C, HDL-C and TG ranged from 3.70-4.37 mmol/L, 2.17- 2.70 mmol/L, 0.94-1.14 mmol/L, 1.07-1.26 mmol/L respectively. In general, girls had higher TC, LDL-C and HDL-C levels. There was no significant difference in the TG levels between boys and girls. Thirty-three percent of the girls and 22% of the boys had TC level _4.4 mmol/L, the level at which dietary intervention is recommended …

The Biomechanical Analysis Of Two Types Of Place Kicks: The Toe And Instep Kicks, Kaylynn Albers

Masters Theses

This study described the biomechanical differences between two styles of the place kick; the toe kick and instep kick. The biomechanical variables included joint angles, velocities, and displacements. Five high school age subjects kicked five trials of the toe kick and five trials of the instep kick at both 20 and 35 yards. The place kicks were filmed with a high speed camera, digitized and analyzed with peak 4.2 computer software.

The findings for joint angles were consistent with those found in the literature. The velocity for the kicking foot and the ball were lower in this study than found …

Co-Sensitization Of Dopamine And Serotonin Receptors Occurs In The Absence Of A Change In The Dopamine D1 Receptor Complex After A Neonatal 6-Ohda Lesion, Li Gong

Electronic Theses and Dissertations

To test whether SKF 38393 could ontogenetically sensitize dopamine (DA) D$\sb1$ receptors and whether this sensitization would be associated with biochemical changes, intact and neonatal 6-hydroxydopamine (6-OHDA)-lesioned rats (200 $\mu$g i.c.v.) were treated daily from birth with SKF 38393 (3.0 mg/kg i.p. x 28 days) or its vehicle. In DA D$\sb1$ neonatally sensitized 6-OHDA rats, enhanced locomotor responses were observed with the first SKF 38393 challenge dose (3.0 mg/kg i.p.) at 6 weeks. This response increased further with weekly SKF 38393 treatments. Enhanced stereotyped behaviors were seen in both lesioned and sensitized rats at 8 weeks. There was no change …

A Comparison Of Four Muscle Relaxant Techniques And Their Incidence Of Postoperative Myalgia In Ambulatory Patients, William James Garske Jr.

Community & Environmental Health Theses & Dissertations

Postoperative myalgia was measured 24 and 72 hours following the administration of four different anesthetic regimens to 36 patients undergoing outpatient or 23-hour admission procedures. Each patient, ASA class I or II, was to undergo procedures of limited duration, 30 to 90 minutes, and surgical stimulation, including procedures such as knee arthroscopy, hernia repair, and breast biopsy. Anesthesia was induced with propofol 1.5 mg/kg, fentanyl 50 mcg, and maintained with O₂ , N₂O, and isoflurane. Group I (n=20), the control, received no muscle relaxant and was maintained with mask ventilation. Group II (n=5) received succinylcholine 1.5 mg/kg …

The Degree Of Exposure To Anesthetic Nitrous Oxide Waste Gas In The Operating Room During Various Surgical Procedures, Kathryn Ann Longworth

Community & Environmental Health Theses & Dissertations

Halsey (1991) summarized the underlying reasons for continuing concern about the problem of waste anesthetic gases. Careful and systematic monitoring studies indicate that individual trends in anesthetic pollution levels are not as low as was confidently predicted 10 years ago, when scavenging devices became commonplace. Second, there are now clear legal requirements for assessment of the situation. It is estimated that each year more than 200,000 health professionals are occupationally at risk of illness as a consequence of chronic exposure to low doses of waste anesthetic gases (Rogers, 1986).

These contaminants are suspected pf being ~eratogenic, carcinogenic, mutagenic, and embryo-lethal. …

Microscopic Colitis: A Diagnosis To Consider, S Hamid, W Jafri, Z Abbas, H Shah, S Abid, H Sheikh, A Hussainy, H Khan

Section of Gastroenterology

Microscopic colitis is a syndrome of chronic watery diarrhoea for which no cause can be identified other than the presence of diffuse, chronic inflammation in the lamina propria on colonic biopsy. Endoscopically and radiologically the colon appears normal. We studied case records of 215 patients presenting to our institution over a three year period with chronic diarrhoea. Nineteen patients were included in the study where two pathologists agreed on the presence of chronic inflammation on colonic biopsies. All patients had watery diarrhoea with urgency. Stool examination, laboratory indices, radiology of the large and small bowel and colonoscopy were normal in …

The Effect Of The Cooper Wellness Program In Promoting Long- Term Lifestyle Behavior Changes, Ernesto P. S. Medina Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Most research on health behavior change programs examines their effectiveness in producing initial behavior changes, but fails to evaluate long-term maintenance of those changes. This study examined the effectiveness of the Cooper Wellness Program (CWP) in Dallas, Texas, in promoting maintenance of lifestyle behavior changes for one year or longer in the areas of diet, exercise, and stress management.

The CWP offers an intensive live-in lifestyle behavior modification program in four-, seven-, or 13-day formats. Data were collected from 223 individuals who attended the CWP between January, 1989, to February, 1992. The study addressed the following areas: 1) long-term maintenance …
