The direct fluorescent antibody technique was used for detection of "specific" antigen in leukocytes of cattle with different forms of leukomia. Using fluorescein isothicoyanate-labeled immunoglobulins from colosterum of cows hyperimmunized with leukocyte mass from cattle with acute leukemia (hemocytobastosis), the "specific" antigen was detected in the cytoplasm of lymphoid and myeloid cells of animals with this and other forms of leukemia. This antigen was not detected in nuclear cells of the peripheral blood wither in normal animals or in animals with non-leukemic diseases (brucellosis, tuberculosis, various helminthic diseases) accompained by qualitative and quantitative changes in the blood similar to those leukemia.

Repeated blood cultures were negative in a six-year-old boy with high septic temperature. Rheumatoid arthritis, typhoid and brucellosis were excluded. There was no evidence of leukaemia (bone-marrow tests). There was hepatomegaly with increased transaminase activity. Cortisone treatment was begun for suspected collagen disease. Several liver needle biopsies at first revelaed increasingly severe necrotising changes, predominantly in the centres of the acini. There were no parasites demonstrable histologically. The spleen was increased in the isotope scan but, covered by the liver, not definitely palpable. Diagnosis of mediterranean Kala-Azar disease was then suspected (the parents reporting a camping holiday in Yugoslavia) and finally proven serologically. The previously treatment-resistant disease improved dramatically after administration of trivalent antimony (Fuadin).

The measurement of serum sialic acid in sera from individuals with leukemia, breast, gastrointestinal, lung and bladder cancers, brucellosis and manic depression is described. The serum sialic acid levels were also examined in mice bearing Landschutz ascites tumours. The presence of sialic acid-enriched glycopeptides in serum was shown. The results indicate that while sialic acid may be significantly elevated in sera of some tumour-bearing individuals, it is not solely tumour-derived. Its application as a tumour marker is limited and requires critical analysis.

In a pilot survey to compare the relative prevalence of three diseases in apparently healthy White Fulani Zebu (WFZ) cattle slaughtered in Nigeria, sera from 80 randomly selected animals with no significant gross lesions on ante mortem and post mortem inspection were examined for antibodies to Brucella abortus, Dermatophilus congolensis and bovine leukaemia virus. Of the samples screened, 5.0, 8.8 and 2.0% showed serological evidence for brucellosis, cutaneous streptothricosis and bovine leukosis respectively.

This paper chronicles developments in the laboratory of Dr. Bruce Chabner during the period 1978-1981. Initial work demonstrated that methotrexate is taken up by human breast cancer cells by a high affinity, carrier-mediated energy-dependent transport system similar to that described in murine leukemia cells. Conversion of methotrexate to a high molecular weight polyglutamate metabolite was also demonstrated to occur in human breast cancer cells. Polyglutamates became the predominant form of intracellular drug, both free in the cytosol and bound to dihydrofolate reductase, during a 24 h exposure to clinically achievable methotrexate concentrations. Intracellular retention of polyglutamates led to prolonged suppression of thymidine synthesis and loss of cell viability after removal of extracellular drug. This work identified methotrexate polyglutamates as biologically active enzyme inhibitors in human tumor cells and launched a series of investigations on the interaction of these derivatives with folate-requiring enzymes.

Human brucellosis is an important animal transmitted disease of man. Although, the cases have been recorded all over the world, the prevalence is higher in developing countries. Lack of sufficient knowledge about the disease among the physicians, its under-diagnosis or misdiagnosis and absence of effective prevention and management strategies are attributed to the widespread of the disease. Increase in the occurrence of animal brucellosis has also resulted indirectly in an increase in the prevalence of human infection. Absence of characteristic clinical symptoms, chronic nature of the infection and difficulty in isolation of the causal agent from the patients make the diagnosis of the disease more difficult. The serological tests employed for diagnosing human brucellosis vary in terms of their sensitivity and specificity. Therefore, a combination of serological tests is desirable. Currently no vaccine is available against human brucellosis, which could check the spread of the disease effectively. It is suggested that clinicians investigate the cases of pyrexia of unknown origin (PUO) for brucellosis. It is desirable that specimens from cases of tuberculosis, typhoid, rheumatoid arthritis, urogenital infections, kala-azar, cirrhosis, bacterial endocarditis, leukemia and filariasis should also be screened for brucellosis in man. The cases of meningitis of unestablished etiology as the cases of human brucellosis are often misdiagnosed as cases of typhoid or tuberculosis.

Periodic fever syndromes are a group of diseases characterized by episodes of fever with healthy intervals between febrile episodes. The first manifestation of these disorders are present in childhood and adolescence, but infrequently it may be presented in young and middle ages. Genetic base has been known for all types of periodic fever syndromes except periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA). Common periodic fever disorders are Familial Mediterranean fever (FMF) and PFAPA. In each patient with periodic fever, acquired infection with chronic and periodic nature should be ruled out. It depends on epidemiology of infectious diseases. Some of them such as Familial Mediterranean fever and PFAPA are common in Iran. In Iran and other Middle East countries, brucellosis, malaria and infectious mononucleosis should be considered in differential diagnosis of periodic fever disorders especially with fever and arthritis manifestation. In children, urinary tract infection may be presented as periodic disorder, urine analysis and culture is necessary in each child with periodic symptoms. Some malignancies such as leukemia and tumoral lesions should be excluded in patients with periodic syndrome and weight loss in any age. After excluding infection, malignancy and cyclic neutropenia, FMF and PFAPA are the most common periodic fever disorders. Similar to other countries, Hyper IgD, Chronic Infantile Neurologic Cutaneous and Articular, TRAPS and other auto-inflammatory syndromes are rare causes of periodic fever in Iranian system registry. In part 1 of this paper we reviewed the prevalence of FMF and PFAPA in Iran. In part 2, some uncommon auto-inflammatory disorders such as TRAPS, Hyper IgD sydrome and cryopyrin associated periodic syndromes will be reviewed.

An immunochromatographic test system has been developed for the simultaneous rapid multiplex serodiagnostics of bovine brucellosis, tuberculosis, and leukemia. The test system is based on the use of a conjugate of gold nanoparticles with the chimeric protein Cysteine-A/G and three analytical zones with immobilized pathogen antigens: Brucella abortus lipolysaccharide, recombinant proteins MPB64 and MPB83-MPB63 of Mycobacterium bovis, and recombinant protein p24 of the bovine leukemia virus. Prototypes of the test system were tested on 98 samples of sera from healthy and infected animals. The diagnostic sensitivity of the developed test system was 92% for brucellosis, 92% for tuberculosis, and 96% for leukemia. False positive test results were not observed.
