The structure of the lachrymal glands of the domestic fowl and of the duck.

The histology of the lachrymal glands of the duck and fowl is similar. In both birds the gland is a compound tubulo-acinar structure, lobulated and invested by a thin connective tissue capsule. Foci of lymphocytes, but few plasma cells, are found in the glands. Moderately acidic mucosubstances predominate in the gland of the fowl whereas sialomucins are found in that of the duck. Neutral lipids were detected only in the gland of the fowl.

Specific antibody production against a soluble antigen in the Harderian gland of the domestic fowl.

Three groups of chickens were immunized with bovine serum albumen (BSA). One group received the antigen i.v., the second had BSA dropped into the orbit and the third group was immunized both systemically and by topical application of BSA. Agar-gel diffusion studies showed antibodies to BSA to be present in the tears and sera of the first and third groups but only in the tears of the second group. Immunofluorescence revealed positive anti-BSA staining in lymphoid cells of the spleens of the first and third groups and in plasma cells of Harderian glands of all three groups. It is concluded that systemic and/or topical applications of BSA affect the tears and Harderian gland whereas only systemic injections produce an effect in the spleen and serum. The Harderian gland may have an important part to play in the local immunologic mechanism of the eye and upper respiratory tract of the fowl.

Cholesterol screening in the emergency department.

OBJECTIVE: To determine the feasibility of providing cholesterol screening in the emergency department (ED) and to determine compliance with follow-up recommendations. DESIGN: A prospective observational study. SETTING: The Ambulatory Care and Treatment Section of the George Washington University Medical Center ED. PATIENTS/PARTICIPANTS: All patients seen in the Ambulatory Care and Treatment Section of the ED who were 18 years of age or older and who were residents of the metropolitan Washington, D.C., area were eligible to participate. During the six-month study period, 660 patients were asked to participate and 539 (82%) agreed. INTERVENTIONS: Fingerstick cholesterol measurements were performed on all participants. Participants who had elevated cholesterol levels, as determined by the National Cholesterol Education Program guidelines, were scheduled for a six-week follow-up visit in the Lipid Research Clinic, where repeat fingerstick cholesterol measurements were performed. Those participants with elevated cholesterol levels were instructed to follow up with their primary care physicians. Compliance with follow-up was assessed by a telephone contact four months after the initial ED visit. MEASUREMENTS AND MAIN RESULTS: Of the 539 participants, 100 (19%) were found to have elevated cholesterol levels. Fifty-three (53%) returned for the six-week follow-up visit. Of the 53 who returned, 7 (13%) had normal and 46 (87%) had elevated cholesterol levels. Of the 46 participants with elevated cholesterol levels, 15 (33%) reported four months after their ED visit that they had received further follow-up care. CONCLUSIONS: Cholesterol screening in the ED is feasible, but compliance with follow-up is less than desirable.
