The method used to produce "Connaught" tuberculin purified protein derivative (PPD) is described. The tuberculin PPD for the multiple-puncture method was shown to be stable for at least 24 months at 5 C; tuberculin PPD for the intracutaneous method was shown to be stable at 5 C and 24 C for a period of 18 months in the presence of Tween 80. Evans blue or brillant vital red was added to tubercul...

The anti-tumor effect of immunization with heat-killed Mycobacterium tuberculosis (Tbc) and Tuberculin (PPD)-coupled syngeneic tumor cells was examined in vivo. Three tumor cell lines were employed. Immunization of Tbc-primed BALB/c mice with PPD-coupled syngeneic Meth-A tumor cells displayed a potent anti-tumor effect on viable Meth-A cells inoculated subcutaneously. Neither PPD-coupled LLC (L...

BACKGROUND Postpartum depression (PPD) could affect ~10% of women and impair the quality of mother-infant interactions. Currently, there are no objective methods to diagnose PPD. Therefore, this study was conducted to identify potential biomarkers for diagnosing PPD. MATERIALS AND METHODS Morning urine samples of PPD subjects, postpartum women without depression (PPWD) and healthy controls (H...

BACKGROUND The purpose of this study was to analyze the characteristics of cracked teeth and to evaluate pulp status according to periodontal probing depth (PPD). METHODS A total of 182 cracked teeth were included. The location and type of the cracked teeth, age and gender of the patients, restoration type, pulp status, PPD, and radiographic findings were analyzed. RESULTS Mandibular second...

BACKGROUND The impact of intimate partner violence (IPV) on postpartum depression (PPD) has been reported in various countries by many studies. However, the association between IPV and PPD in Japan has been scarce. In addition to the limited number of research on the relationship between IPV and PPD, the number of women seeking help from IPV support centers has been steadily increasing in Japan...

Despite highly successful eradication efforts in several countries, Mycobacterium bovis infection of cattle remains a significant health concern worldwide. Immune mechanisms of resistance to and/or clearance of M. bovis infection of cattle, however, are unclear. Recent studies have provided evidence supporting a role for CD4(+), CD8(+), and gammadelta TCR(+) T cells in the response of cattle to...

Hypersensitivity to para-phenylenediamine (PPD) and related compounds induced by temporary black henna tattoos has become a serious health problem worldwide. Different patterns of sensitization with various clinical aspects are described in literature due to PPD associated to henna tattoo and these manifestations are likely correlated with the immunological and dermatological pathomechanisms in...

PURPOSE The concept of gingival biotype has been used as a predictor of periodontal therapy outcomes since the 1980s. In the present study, prospective and controlled experiments were performed to compare periodontal pocket depth (PPD) reduction and gingival shrinkage (GSH) after scaling and root planing (SRP) according to gingival biotype. METHODS Twenty-five patients diagnosed with chronic ...

BACKGROUND Postpartum depression is a well-known phenomenon that occurs in about 10% of births and affects the quality of life of the mother as well as the family. As in other cases of depression, under-diagnosis of PPD may keep patients from getting proper care and increase their physical and emotional distress. OBJECTIVES To identify patients with PPD and to describe their consultation patt...

p-Phenylenediamine (PPD) is a component of certain henna tattoo and hair dye formulations. Human exposure to PPD containing products is associated with the development of T-cell mediated allergic contact dermatitis. Antigen-specific T-cells from allergic contact dermatitis patients are activated with either PPD or Bandrowskis base (BB), the metabolized trimer of PPD. In non-allergic individuals...
