Abstract
Production of quality jute fibre primarily depends on the retting process of jute. However, the quality of retting water is of great concern because of the scarcity of available water bodies for retting. A study conducted on physico-chemical and microbiological changes in retting water (pre- and post-retting) from four intensively jute-growing districts namely Nadia, North 24 Parganas, Hooghly and South Dinajpur of West Bengal, India, during jute retting. The post-retting water samples recorded lower pH (6.22 to 7.08) and higher EC (electrical conductivity) (0.509 to 0.850 ds/m) compared with pre-retting water samples (pH 6.63 to 7.44; EC 0.197 to 0.330 ds/m) collected from all the four districts under study. The biological oxygen demand (BOD) and chemical oxygen demand (COD) increased several folds in the post-retting water samples indicating very high microbial growth and activities and depleted oxygen level compared with pre-retting water. The Ca + Mg (calcium + magnesium) content in pre-retting water was high (24.15 to 36.60 ppm) which raised further (61.30 to 103.67 ppm) in post-retting water, while the bicarbonate content also increased and ranged between 2.72 and 6.81 me/l in post-retting water compared with its status in pre-retting water (1.30 to 3.15 me/l). The post-retting water was found to be a rich source of nutrients like nitrogen (N), phosphorus (P), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) which increased substantially because of jute retting as compared with their status in pre-retting water. The population of pectinolytic, xylanolytic, cellulolytic and ligninolytic bacterial cfu (colony forming unit) increased by 1.5 times in post-retting water as compared with pre-retting water, because these specific bacterial population were involved in the degradation of pectin, xylan, cellulose and lignin during retting of jute. Thus, post-retting water can be judiciously used as a potent source of primary, secondary and micronutrients for succeeding crops besides having higher BOD and COD as a result of higher microbial growth related to jute retting.

Abstract
Recent molecular analysis has shown the evidence which claims human interstitium as a new organ in the body. However, in routine hematoxylin and eosin stained sections, these spaces are not evident and thus probably have not received much attention. The implications of this discovery in oral pathology, especially cancer metastasis are immense. Although the structure and components of oral mucosa differ from that of skin and gastrointestinal tract (GIT) in various aspects, if the above findings are established in the oral submucosa, various oral diseases related to fluid and fluid dynamics may perhaps be reviewed. In this editorial, we have made attempt to hypotheti-cally consider the various possible implications of 'third space' in the field of dentistry. Keywords: Interstitium, Oral cancer, Oral pathology.

Abstract
Juvenile ossifying fibroma is a benign fibro-osseous lesion commonly affecting the extra-gnathic craniofacial skeleton of the young individuals. The psammomatoid and trabecular variants are its two histopathological subtypes having distinctive clinico-pathological characteristics. Secondary aneurysmal bone cysts are frequently reported to arise in the pre-existing fibro-osseous lesions but rarely reported in the psammmomatoid variant of the juvenile ossifying fibroma. Such hybrid lesions, especially massive in size, tend to exhibit a greater aggressive growth potential and higher recurrence rate and mandate complete surgical removal of the lesion along with a long-term follow-up. The objective of this case report was to present a rare incident of recurrent psammomatoid ossifying fibroma associated with a secondary aneurysmal bone cyst in the maxillary jaw bone of a young patient and review the similar published reports in the English literature.

Abstract
Oropharyngeal candidosis (OPC) is an opportunistic fungal infection that is commonly found in HIV-infected patients, even in the twenty-first century. Candida albicans is the main pathogen, but other Candida species have been isolated. OPC usually presents months or years before other severe opportunistic infections and may indicate the presence or progression of HIV disease. The concept of OPC as a biofilm infection has changed our understanding of its pathobiology. Various anti-fungal agents (both topical and systemic) are available to treat OPC. However, anti-fungal resistance as a result of the long-term use of anti-fungal agents and recurrent oropharyngeal infection in AIDS patients require alternative anti-fungal therapies. In addition, both identifying the causative Candida species and conducting anti-fungal vulnerability testing can improve a clinician's ability to prescribe effective anti-fungal agents. The present review focuses on the current findings and therapeutic challenges for HIV-infected patients with OPC.

Abstract
Giant cell lesions of the jaws represent distinctive clinico-pathological spectrum. They manifest as peripheral and central lesions, occurring as solitary growths to involving multiple regions of the jaw. The present report presents a unique case of giant cell lesions of the jaws, wherein a peripheral giant cell granuloma recurred exclusively as a central giant cell lesion in a young patient. The recurrence was noted after a time-span of 3 years since the diagnosis and surgical excision of the peripheral lesion. Biochemical investigations were advised to rule out the possibility of hyperparathyroidism. Following a confirmed diagnosis of central giant cell granuloma, not associated with any other systemic conditions, an apt treatment plan was devised for an early rehabilitation of the patient.

Abstract
A long-term fertilizer experiment was initiated in 1971 in sandy loam soil (Eutrochrept) of Barrackpore, West Bengal to study the effects of applying organic and inorganic sources of nutrients on yield of jute-rice-wheat system and soil health. The unfertilized soil supported yields of 0.8 t ha-1 of jute fibre, 1.5 t ha-1 of rice grain and 0.7 t ha-1 of wheat grain (average yield of 42 years). Application of 150% recommended NPK through chemical fertilizers produced maximum yields of jute (2.1 t ha-1), rice (3.8 t ha-1) and wheat (2.8 t ha-1). The yields obtained with 150% NPK fertilizers were 5%, 2.7% and 12% higher than that with 100% NPK fertilizers +FYM. Combined application of 100% NPK fertilizers and FYM, however, increased soil organic carbon, available nitrogen, phosphorus and potassium from 5.60 to 8.90 g kg-1, 270 to 316 kg ha-1, 40.7 to 120 kg ha-1 and 139 to 236 kg ha-1 respectively. Maximum DTPA-extractable micronutrients in soil were also observed with 100%NPK fertilizers+FYM. Applying FYM together with NPK fertilizers increased microbial biomass from 221 to 435 mg kg-1 and microbial quotient from 3.95 to 4.89 with concomitant increase in dehydrogenase, phosphatase and fluorescein-diacetate-hydrolyzing activities in the soil. The acid phosphatase activity (139 to 275 μg PNPg-1 h-1) was much lower than alkaline phosphatase activity (479 to 616 μg PNPg-1 h-1). The enzymes assayed showed significant correlation with microbial-C and organic C. Beneficial effects of integrated nutrient management (NPK+FYM) on soil health were reflected on the yields of all the crops.

Abstract
Primary retroperitoneal tumours pose a diagnostic dilemma and therapeutic challenges because of their location and late detection. Localized Castleman Disease (CD) in retroperitoneal location is a rare occurrence, with incidence of only 4% cases occurring in diverse locations like retroperitoneum. A rare case of unicentric localized Castleman Disease localized in broad ligament is hereby reported which was clinically & radiologically suspected as broad ligament leiomyoma but finally diagnosed as Castleman’s Disease, hyaline vascular type in a young female posing a diagnostic challenge both for the pathologist and clinician. Definite diagnosis is essential as complete surgical excision in case of unicentric Castleman’s Disease has good prognosis after resection.

Abstract
Candida species present both as commensals and opportunistic pathogens of the oral cavity. For decades, it has enthralled the clinicians to investigate its pathogenicity and to improvise newer therapeutic regimens based on the updated molecular research. Candida is readily isolated from the oral cavity, but simple carriage does not predictably result in development of an infection. Whether it remains as a commensal, or transmutes into a pathogen, is usually determined by pre-existing or associated variations in the host immune system. The candida infections may range from non-life threatening superficial mucocutaneous disorders to invasive disseminated disease involving multiple organs. In fact, with the increase in number of AIDS cases, there is a resurgence of less common forms of oral candida infections. The treatment after confirmation of the diagnosis should include recognizing and eliminating the underlying causes such as ill-fitting oral appliances, history of medications (antibiotics, corticosteroids, etc.), immunological and endocrine disorders, nutritional deficiency states and prolonged hospitalization. Treatment with appropriate topical antifungal agents such as amphotericin, nystatin, or miconazole usually resolves the symptoms of superficial infection. Occasionally, administration of systemic antifungal agents may be necessary in immunocompromised patients, the selection of which should be based upon history of recent azole exposure, a history of intolerance to an antifungal agent, the dominant Candida species and current susceptibility data.

Abstract
The majority of oral diseases present as growths and masses of varied cellular origin. Such masses may include simple hyperplasia, hamartoma, choristoma, teratoma, benign or malignant neoplasms. The distinguishing features of hamartomatous lesions are not certain, and often these non-neoplastic masses are indiscreetly denoted as neoplasms without weighing their pathology or biological behaviour. Essentially, understanding the dynamics of each of these disease processes forms an integral part of the appropriate treatment planning.

Abstract
Reviewing the research in the field of oncolytic virus therapy (OVT) of the past two decades, it is inspiring to see the enormous amount of success accomplished by the scholars of this innovative therapeutic technique. Though the experimental trials have been ongoing from 1990s, however, it took a leap forward with approval of the clinical trials in China, 2005. The world's first oncolytic virus to be approved by their government was adenovirus (with E1B 55K gene deletion) for head and neck cancer therapy along with chemotherapy.

Abstract
Background: Fixation is the essential step in histopathological processing of tissues. Since formalin is a corroborated biohazard, its routine use as a fixative is a major health and safety concern and hence the quest for safer alternatives is envisaged. Natural sweeteners like jaggery and honey have proved to be effective tissue preservatives over 24 h. This pioneer eco-idea needs further research to expand its application. Aim: (1) To evaluate the fixative property of jaggery and honey over 6 months and ascertaining the results using hematoxylin and eosin stain (H and E). (2) To evaluate the compatibility of jaggery and honey fixed tissues for special stains - Periodic acid Schiff (PAS) and Masson–Trichrome (MT). Materials and Methods: Equal bits of commercially available animal mucosae were preserved in 30% jaggery, 20% honey, and 10% buffered formalin (control) over 6 months at intervals. Following which, tissues were subjected to routine H and E, special stains - PAS and MT using standard operating procedures established in our group. Results: Formalin, jaggery, and honey yielded satisfactory results post 6 months for H and E and special stains, jaggery was comparable to formalin in tissue preservation. Conclusion: We propose the use of eco-friendly jaggery and honey as alternatives to formalin for long term tissue preservation.

Abstract
BACKGROUND Keratins are the most abundant proteins and are characteristic findings in many epithelial pathologies, making it a diagnostically important marker, both histopathologically and immunohistochemically. Since, immunohistochemistry is an expensive diagnostic tool, special stains to detect the degree of keratinization could serve as a faster and economic option. The aim of the present study was to compare the efficacy of special stains for keratin with standard hematoxylin and eosin stain (H and E). Objectives include: (i) To subject the diagnosed cases of keratin disorders to the selected special stains: Ayoub-shklar method, Dane-Herman method, Alcian blue -periodic acid Schiff 's (PAS), rapid papanicolaou (PAP) and Gram's stain. (ii) To compare the staining specificity and staining intensity of special stains with respect to routine hematoxylin and eosin (H and E) stain. (iii) To compare the efficacy of special stains to routine H and E stain in identification of the type of keratin present in the selected cases. MATERIALS AND METHODS A total of 80 cases of known pathology for keratin were retrieved from the department archive, which included 10 each of normal gingiva, hyperkeratosis, squamous papilloma, verrucous hyperplasia, verrucous carcinoma, well-differentiated squamous cell carcinoma, orthokeratinized odontogenic cyst and keratocystic odontogenic tumors. Six sections of 4 µ each from the paraffin blocks were made, stained with H and E and the special stains and these were evaluated by 2 pathologists based on the modified scoring criteria from Rahma Al-Maaini and Philip Bryant 2008. RESULTS The results were tabulated using Chi square and kappa statistics. The statistical values for identification of the type of keratinization was insignificant showing that ortho and parakeratinized epithelia could be correctly identified by both H and E as well as all the special stains. Furthermore, all the special stains showed a positive result and statistical significance (P < 0.001) with respect to the staining of keratin. CONCLUSION To conclude, though the special stains distinctly stained the keratin with a higher intensity, H and E proves to be overall better stain with respect to specificity.

Abstract
Gene and environmental factors are instrumental in genesis of complex and wide range of disorders and syndromes. The newer gene sequencing and other advanced technologies have made our previous knowledge of genetic etiopathogenesis of various disorders more transparent. Single gene disorders refer to the disorders caused due to mutations in a single gene and a fair number of these manifest as craniofacial defects and anomalies. This review is an attempt to give a detailed insight into the varied single gene disorders and syndromes with an emphasis on dental implications.

Abstract
The chromosomal disorders are individually rare, but collectively they are common whereas the multifactorial disorders are the most common form of genetic disorders. The chromosomal anomalies typically arise from alterations in the DNA containing chromosomal regions and can be reliably detected by karyotype analysis, whereas the multifactorial disorders demonstrate multi-gene as well as environmental interactions. Both the chromosomal and multifactorial disorders may manifest signs and symptoms such as a combination of birth defects, physical disabilities, challenging behavior and certain craniofacial defects as well, the knowledge of which can aid in a better patient management in everyday practice of dentistry.

Abstract
Background: Fallopian tubes are common surgical specimen in the pathology laboratory; still there is a lack of data to describe the frequency of various histological fi ndings. The aim and objectives of this study was to describe the various histopathological fi ndings of fallopian tubes. Materials and Methods: Two thousand fi ve hundred and seventy fi ve cases where fallopian tubes were removed either separately or along with other female genital tract organs were studied retrospectively and their histopathological fi ndings documented. Results: Ectopic pregnancy comprised maximum number of cases closely followed by salpingitis. Primary neoplastic lesions were rare as compared to secondary malignancies. Serial sections of fallopian tube and sections from representative areas are essential for a pathologist so that the diagnosis of these pathological entities is not missed. Conclusion: Though the fallopian tubes remain unremarkable in majority of the surgical pathological specimens, it must be subjected for histopathological examination to demonstrate the pathological lesions.

Abstract
Malignant transformation of fibrous dysplasia is rare, occurring in less than 1% of cases with a mean lag period of 13.5 years. We report a case of Osteogenic Sarcoma with chondroid differentiation in a pre-existing Fibrous Dysplasia occurring within one year of surgical resection and without any history of exposure to radiation. To the best of our knowledge and extensive search of literature, malignant transformation of Fibrous Dysplasia in such a short period of time, and without history of radiation exposure has never been reported from India.Journal of Pathology of Nepal (2012) Vol. 2, 335-337DOI: http://dx.doi.org/10.3126/jpn.v2i4.6891

Abstract
The comparative dosimetry of GammaMed (GM) Plus high-dose rate brachytherapy source was performed by an experiment using 0.1-cc thimble ionization chamber and simulation-based study using EGSnrc code. In-water dose measurements were performed with 0.1-cc chamber to derive the radial dose function (r = 0.8 to 20.0 cm) and anisotropy function (r = 5.0 cm with polar angle from 10° to 170°). The nonuniformity correction factor for 0.1-cc chamber was applied for in-water measurements at shorter distances from the source. The EGSnrc code was used to derive the dose rate constant (Λ), radial dose function g(L)(r) and anisotropy function F(r, θ) of GM Plus source. The dosimetric data derived using EGSnrc code in our study were in very good agreement relative to published data for GM Plus source. The radial dose function up to 12 cm derived from measured dose using 0.1-cc chamber was in agreement within ±3% of data derived by the simulation study.

Abstract
Accessing medical information in mobile devices such as PDAs and mobile phones is becoming widespread. Since these devices do not have the same rendering capabilities as of desktop computers, it is necessary for medical information to be fragmented for proper presentation on these types of devices. In this paper, we propose an architecture for displaying medical information in PDA. In the proposed system, a server extracts the information, categorizes the information in order of its relevance for diagnosis, and dynamically generates a hierarchical view of the relevant information based on certain medical domain knowledge. Displaying image and graphics data in PDA poses several challenges. The proposed system supports an image visualization tool, which interactively displays an image or a portion of an image in user's PDA. This visualization tools increases the resource utilization of PDA by offloading a part of the computation to the server. A suitable caching scheme is incorporated for optimum utilization of communication channel bandwidth.

Abstract
The article is based on a four-year project during which Primary Health Care (PHC) nurses worked with women's groups in their areas. The aim of the study was to explore the involvement of PHC nurses in economic empowerment, both in terms of health promotion and in terms of the PHC approach. In particular the objectives were to establish whether nurses could lead economic empowerment groups, whether such groups could establish adequate external links and become financially viable. Eleven groups were used as case studies, and a cross-case analysis was done in terms of the three objectives. It was found that between the women and the nurses, adequate leadership existed for the groups to function well. Very limited external linkages were established, notwithstanding efforts in this regard. Nine out of 11 groups contributed to financial welfare of their members after 18 months, but a range of problems with regard to financial viability are identified.

Abstract
The aim of this study is to estimate the room-scatter correction when measuring air kerma rate of an HDR 192Ir brachytherapy source by in-air calibration. The variation in scattered radiation due to the specially designed jig and from the room walls was also studied. Two therapy ion chambers of volume 0.1 cm3 and 0.6 cm3 were used in the present study. Air kerma was measured by placing the source at several distances between 10 cm and 20 cm from the chamber. The scatter radiation was determined by superimposing the theoretically derived model curve of known scatter (based on the inverse square law) over the plot of measured air kerma strength values. The scatter radiation was estimated in terms of percentage of the primary radiation at 10 cm measurement distance. The scatter estimated by the 0.6 cm3 chamber at two positions was 0.33% and 0.59%, respectively. Similarly the scatter estimated at two other positions by the 0.1 cm3 chamber was 0.58% and 1.11%. This variation in scatter with position as well as with the chamber was due to the varying scatter contribution from components of the measurement set-up. The scatter radiation becomes constant at a distance greater than 100 cm from the walls of the room. We conclude that a fixed chamber with changing source positions should be used in multiple-distance measurement of air kerma rate when using a measurement jig.

Abstract
A series of 12 studies (five historic cohort and seven randomized trials) examined clients in community settings in Southern Ontario suffering from a variety of chronic physical and mental health conditions. These studies are appraised using a framework for evaluating possible outcomes of economic evaluation. In the 12 studies, sample composition and size varied. Each study was designed to quantify the well-being outcomes and expenditures associated with different community-based approaches to care provided in the context of a system of national health insurance. As a collective, these studies represent increasing methodological rigour. Multiple-perspective client well-being outcome measures were used. In two studies, caregiver burden also was analysed. A common approach to quantification and evaluation of expenditures for service consumption was used in all 12 studies. The nature of community-based health services (health vs. disease care orientation) was found to have direct and measurable impact on total expenditures for health service utilization and client well-being outcomes. In most cases, a recurring pattern of equal or better client outcomes, yet lower expenditures for use of community based health services, was associated with well-integrated health oriented services. Integrated services aimed at factors which determine health are superior when compared to individual, fragmented, disease oriented, and focused approaches to care. The main lessons from the 12 studies are that it is as or more effective and as or less expensive to offer complete, proactive, community health services to persons living with chronic circumstance than to provide focused, on-demand, piecemeal services. Complete services would have a psychosocial and mental health focus included with the physical care approach. Furthermore, people with coexisting risk factors (age, living arrangements, mental distress and problem-solving ability) are the ones who most benefit at lower expense from health oriented, proactive interventions.

Abstract
In the 1970s, McMaster University, Hamilton, introduced self-directed learning (SDL) to its undergraduate nursing program. This innovation was prompted by a fundamental belief in the importance of nurse empowerment and the link between empowerment and SDL. The empowerment of nurses, it was believed, was critical to the improved health and welfare of patients. In the 1990s, faculty and alumni have perceived another benefit to SDL: the ability of McMaster graduates to persevere and excel in the face of health care system change.

Abstract
OBJECTIVES To examine the effectiveness of culture sensitivity training for foreign-trained medical graduates licensed to practice in Ontario, Canada. DESIGN A study of pretest-post-test design was conducted to determine the effect of cultural sensitivity training on newly immigrated physicians licensed in Canada. Twenty-four physicians, those who had passed the medical licensing exam in 1996 and had not yet started their residency program, were given 15 hours of cultural sensitivity training and were considered the experimental group. This group was compared with a control group of 24 physicians who had passed the licensing exam and were in the process of completing residency. SETTING University of Toronto. SUBJECTS Foreign-trained medical graduates. RESULTS Both groups completed the Cross-Cultural Adaptability Inventory both before and after the training of the experimental group. Statistical significance in three subscales of the Open-Mindedness/Flexibility, Emotional Resilience and Perceptual Acuity dimensions were demonstrated in the experimental group as compared with the control group. CONCLUSIONS In order for Canada to mould professional and effective physicians great care must be taken in the design and process of cultural sensitivity programmes to enhance both knowledge and skills. Follow-up should be undertaken to compare their effectiveness with the control group.

Abstract
Minority women identify finances and maintaining cultural values as their most commonly experienced stressors at home and in the work-place. A before and after study of ethnic minority women in focus group sessions led by a trained ethnic minority facilitator examined how social and workplace supports, or lack thereof, impact on the individuals' ability to manage daily life. Creative, effective solutions to stressors were identified by the participants. Outcomes were evaluated in terms of the impact of changes on the participants' coping styles in family and work life. Results indicate that a large percentage of women in this study felt discriminated against based on their culture/race, however, this perceived discrimination decreased after the focus groups. The predominant stress management techniques were prayer and music. Family support was the most influential factor in decreasing stress. The family is a major source of support for the working women, acting as a buffer to workplace pressures.

Abstract
AIDS affects everyone, regardless of race, age, or religion; hence, information must be accessible to everyone. This descriptive study identified the need to generate culturally sensitive educational programs and evaluated their effect. Culturally sensitive AIDS educational training was offered to culturally diverse women. Training was conducted by women of the same ethnicity as the women in the group. The facilitators were specially trained on the role of a facilitator and the participatory method of learning. To assess any change in attitude, knowledge, and beliefs regarding AIDS, the questionnaire was administered before and after the training programs. Educational training had a positive effect (p < .05) on participants' attitude and knowledge regarding AIDS; they felt comfortable discussing their concerns in their own language, and with their friends from the same community, and they viewed the resources used as culturally sensitive.

Abstract
Pakistan's health characteristics are worse than those of other Asian countries at similar stages of development. Its mortality rate for children under five is 139 per 1,000, and its maternal mortality is 60 per 10,000. Malnutrition in women and children is widespread; 50 per cent of children under five are stunted. Pakistan's population growth rate of 3.1 per cent per year is among the highest in Asia. The high population growth rate and poor health status of many people call for extensive health care services, but, unfortunately, health services do not reach most of the people of Pakistan. Partly because the training of doctors and nurses is lengthy and expensive, there is an acute shortage of health care providers, especially women. Although female health professionals are preferred for caring for women, cultural constraints inhibit women from seeking education. Such is the multifaceted dilemma in the provision of primary health care in Pakistan.

Abstract
The rapid pace at which biological health breakthroughs and advancements in technology occur is creating unique challenges to health care programmes. The curricula of all health care programmes will need to be set in learning environments where students will be able to develop learning skills that are transportable across situations, over a whole lifetime. This article attempts to focus on self-directed learning (SDL) concepts and the development of a learning contract/plan, including the roles of both the student and faculty in self-learning approaches and contractual development.

Abstract
This survey assessed the ethnocultural proportion of clients (largely seniors) receiving services from three home care health agencies in Southern Ontario. Providers from the three agencies were asked to recall clients served in the previous two weeks and to describe them in terms of race, language, sex, age and disability status. White, English-speaking clients comprised 88.3% of the sample (N = 931). The remaining 11.7% of clients were white, non-English-speaking (7.8%), visible minority (2.8%), francophone (0.77%), indigenous (0.22%) and Hispanic (0.11%). Sixty-three percent of clients were women and 34% men. The majority (66.6%) of clients were over 65 years. The 11.7% of clients who were identified as multicultural in three home care agencies are an under-representation of the multicultural mix of population in the Southern Ontario region, which is 24%. Some recommendations have been offered for a system for ethnocultural data collection for the region and provision of cultural sensitivity training programs to enhance staff knowledge and skills.

Abstract
In view of the increasing emphasis on community-based primary health care, nursing education programs need to identify creative learning strategies to prepare nurses capable of promoting, maintaining and restoring health in diverse populations. The purpose of this descriptive study was to identify the learning outcomes acknowledged by junior baccalaureate nursing students in non-traditional community settings. Data were gathered through semi-structured interviews with the students, through journals kept daily by the students, and from the faculty tutor's anecdotal notes. Analysis of data illustrated concepts from Stewart's conceptual framework for primary health care. Students gained an appreciation of the influence of the social-cultural-political and physical environments on health. They also came to understand the significance of collaborative modes of interaction with recipients of nursing care. Thus, non-traditional community experiences demonstrated effectiveness in enhancing students' understanding of the multiple dimensions of health as well as the necessity for mutuality in nurse-person interactions. Providing varied learning environments in undergraduate nursing programs will produce practitioners who are more responsive to present and future primary health care issues.

Abstract
A simple in vitro nasal mucosal culture model has been developed to measure release of the mast cell specific enzyme tryptase in response to allergen challenge. Patients who were undergoing inferior turbinectomy were skin-tested for commonly inhaled allergens. The mucosa from the inferior turbinates was kept viable using Minimal Essential Medium. Tryptase release into the medium was measured using the Pharmacia Riact Assay. There was a significant increase in tryptase release in response to allergen challenge from the mucosa harvested from skin-test positive patients. Mucosa from skin-test negative patients failed to demonstrate an increase in tryptase release. This could prove to be a useful research model for the study of nasal type I hypersensitivity and drugs that affect it.
