Pengabdian masyarakat ini dilakukan seiring dengan penambahan jumlah kasus COVID-19 berlangsung cukup cepat dan sudah terjadi penyebaran antar negara. Berdasarkan bukti ilmiah, dapat menular dari manusia ke melalui percikan batuk/bersin (droplet). Orang yang paling berisiko tertular penyakit adalah orang kontak erat pasien termasuk merawat COVID-19. Metode digunakan dalam kegiatan menggunakan b...

A highly specific and reproducible antigen-induced, antigen-specific culture and assay system for antibody production by human peripheral blood B lymphocytes has been developed. The system is clearly T cell and monocyte dependent and is independent of exogenous mitogens. The major factors in our ability to trigger specific antibody production with antigen alone have been the use of extremely lo...

A null cell leukemia cell line, THP-5, was established from the peripheral blood of a patient with acute null cell leukemia. THP-5 cells were characterized by the presence of Ia-like antigen and the absence of other cell surface markers examined. Despite the presence of Ia like antigen, THP-5 cells had no stimulating capacity in autologous or allogeneic mixed lymphocyte reaction.

This study examined circulating filarial antigen by monoclonal antibody Og4C3-enzyme-linked immunosorbent assay (ELISA) from 114 men with hydrocele, living in an endemic area. Nocturnal blood and hydrocele fluid were collected and examined for microfilaria. ELISA was performed on serum and hydrocele fluid for detection of antigen. Amongst 114 cases, 5(4.4%) showed microfilaria in blood but none...

Purified fiber antigen of type 5 adenovirus inhibited the multiplication of type 5 adenovirus by 50% when 35 mug of fiber antigen protein was added to 10(6) KB cells in suspension culture. Although the fiber antigen reduced the number of virions adsorbed per cell when a multiplicity of infection of 50,000 plaque-forming units (PFU)/cell was employed, the number of cells infected was not diminis...

The serum concentrations of squamous cell carcinoma antigen (SCC-Ag) obtained from 124 surgically treated primary non-small cell lung cancer patients, including 75 adenocarcinomas (AD) and 49 squamous cell carcinomas (SQ), were studied. The changes in the SCC-Ag concentration, which were obtained before and one month after surgery, were analyzed. The 5-year survival rate of the patients with AD...
