The albumin globulin ratio (A/G ratio) is meant to represent the ratio of alterations in serum proteins, since, in liver disease, globulins (G) rise following serum albumin (SA) decrease. pathophysiological value, its' use has been limited. Alternatively, we have developed an index, the globulin compensation index (GCI) to measure the changes in serum globulins when albumin is decreased. The index is calculated as follows: G - 25 / 35 - SA. The GCI has been tested using retrospective patients' data from the Hospital Universiti Sains Malaysia. Analysis of the data shows that the GCI may be of potential value in showing the actual serum protein status, especially in cases where globulins are decreased along with albumin. Furthermore, globulin rise in cases with reduced albumin was found in 72.3% of cases of hepatic diseases, whereas this finding occurred in up to 32.3% of cases of non-hepatic, systemic diseases.
Beta-thalassaemia major is one of the commonest genetic disorders in South East Asia. The strategy for the community control of beta-thalassaemia major requires the characterisation of the spectrum of beta-globin gene mutations in any multi-ethnic population. There is only a single report of mutation analyses of the beta-globin gene in an isolated Kadazandusun community in Kota Belud, Sabah, Malaysia, which showed the presence of a common 45 kb deletion.
The present study was aimed at the identification of proteins that are differentially expressed in the urine of patients with prostate cancer (PCa), those with benign prostatic hyperplasia (BPH) and age-matched healthy male control subjects. Using a combination of 2DE and MS/MS, significantly lower expression of urinary saposin B and two different fragments of inter-alpha-trypsin inhibitor light chain (ITIL) was demonstrated in the PCa patients compared to the controls. However, only one of the ITIL fragments was significantly different between the PCa and BPH patients. When image analysis was performed on urinary proteins that were transferred onto NC membranes and detected using a lectin that binds to O-glycans, a truncated fragment of inter-alpha-trypsin inhibitor heavy chain 4 was the sole protein found to be significantly enhanced in the PCa patients compared to the controls. Together, these urinary peptide fragments might be useful complementary biomarkers to indicate PCa as well as to distinguish it from BPH, although further epidemiological evidence on the specificity and sensitivity of the protein candidates is required.
Introduction: Virgin coconut oil (VCO) is known for its health and therapeutic benefits. However, the immunomodulatory effects of VCO have not been extensively investigated. Objective: The present study was devoted to examining the effects of VCO on cyclophosphamide (CY)-induced toxicity of lymphoid tissues. Methods: Thirty healthy male Wistar rats were sorted into 5 groups of 6 animals. The first control (NC) group was given distilled water via gavage at 5 ml/kg once daily. The second (CY) group received CY orally at 10 mg/kg/day for 4 weeks. Rats in the other three groups (CV5, CV10, and CV15) were given 10 mg/kg/day CY for 4 weeks, 5 m/kg/day, 10 ml/kg/day and 15 ml/kg/day VCO for 6 weeks, respectively. Rats were sacrificed at the end of 6th week; blood sample from the animals was collected for full blood count and biochemical analysis. The thymus and spleen of each animal was processed for histological examination. Results: The thymus and spleen showed marked reduction in lymphoid cellularity following daily administration of CY. The thymus also showed a marked reduction in the size of the medulla, and the white pulp areas of spleen had reduction in the follicle number and size. Supplementation with 10 ml/kg and 15 ml/kg VCO showed evidence of restoration of both the thymus and splenic lymphoid architecture. The total white cell counts, absolute lymphocyte counts and plasma globulin levels of the VCO groups were significantly increased compared to CY group. Conclusion: VCO displayed potential protective effects on CYinduced histological changes in lymphoid tissues.
Objective. To determine the diagnostic accuracy of placental alpha microglobulin-1 assay and standard diagnostic methods for detecting rupture of membrane. Study Design. Prospective diagnostic study, between June 2011 to November 2011 at a tertiary centre. Initial evaluation included both the standard diagnostic methods for rupture of membranes and placental alpha microglobulin-1 immunoassay. The actual rupture of membranes was diagnosed on review of the medical records after delivery (absence of membrane or a positive pad chart). Main Outcome Measures. Placental alpha microglobulin-1 immunoassay and standard diagnostic methods for diagnosis of rupture of membrane. Results. A total of 211 patients were recruited. At initial presentation, 187 patients (88.6%) had ruptured membranes, while 24 patients (11.4%) had intact membranes. Placental alpha microglobulin-1 immunoassay confirmed rupture of membranes at initial presentation with a sensitivity of 95.7% (179 of 187), specificity of 100% (24 of 24), positive predictive value of 100% (179 of 179), and negative predictive value of 75.0% (24 of 32). By comparison, the conventional standard diagnostic methods had a sensitivity of 78.1% (146 of 187), specificity of 100% (24 of 24), positive predictive value of 100% (146 of 146), and negative predictive value of 36.9% (24 of 65) in diagnosing rupture of membrane. Conclusion. Placental alpha-microglobulin-1 immunoassay is a rapid and accurate method for confirming the diagnosis of rupture of membrane. It was superior to conventional standard diagnostic methods (pooling, nitrazine, and ferning), the nitrazine test alone or fern test alone.
Currently, there are no complete parameters established for serum biochemistry and hematology for the determination of health status of rescued common palm civets (Paradoxurus hermaphroditus). In this study, blood samples were obtained from 18 adults and 15 juvenile civets caught on Singapore Main Island. Significant age-related differences (P<0.05) were noted in the hemoglobin, erythrocyte count, packed cell volume (PCV), total serum protein and globulin concentration in the adult civets showing higher values compared with the juvenile civets. The mean corpuscular volume (MCV), the alkaline phosphatase (ALP) and the phosphorus concentrations were significantly higher (P<0.05) in juveniles compared with adult civets.
Uveitis associated with Ehrlichia canis or Anaplasma platys infections were reported in dogs. However, only two E. canis-infected dogs with hypergammaglobulinemia showed acute blindness were reported. There were limited data of the species of Ehrlichia or Anaplasma and the alteration of serum protein fractions in infected dogs. Thus, the species of causative pathogen were investigated and compared the serum protein fractions between infected dogs associated with anterior uveitis and panuveitis in clinical situations. All 103 studied dogs were brought into the ophthalmology clinic which each dog showed signs of unilateral or bilateral uveitis related to ehrlichial infection. Dogs were divided into anterior uveitis and panuveitis groups. The species of Ehrlichia or Anaplasma were identified using nested-PCR based on the 16S rRNA gene and DNA sequencing from blood samples. The serum protein fractions were analyzed using electrophoresis. Fifty-eight dogs (56.31%) were positive of which E. canis and A. platys were detected in 51 and 7 dogs, respectively. The total serum protein and globulin levels were higher in the infected dogs associated with panuveitis than anterior uveitis while the albumin levels were significantly lower in the panuveitis group. The A/G ratios significantly decreased in both groups. Gamma globulin was detected at high levels in both groups while beta globulin significantly increased in the panuveitis group. Hypergammaglobulinemia was detected in 76.92 and 90.90% of infected dogs associated with anterior uveitis and panuveitis, respectively. Most of the infected dogs associated with panuveitis showed significantly levels of hyperproteinemia, hyperbetaglobulinemia and hypergammaglobulinemia compared with anterior uveitis group. E. canis was found as the major pathogen in infected dogs associated with uveitis in this study.
1. A skin lesion was made in rats by dorsal incision and the insertion of a polythene tube. 2. Over a period of 25 days after wounding, assays were performed for ascorbic acid, DNA, hydroxyproline, methionine, tryptophan, tyrosine and free amino acids in the lesion tissue. 3. The neutral-salt-soluble proteins of the lesion tissue were fractionated on DEAE-Sephadex, with the separation of fibrinogen and gamma-globulin from a serum protein fraction. 4. Over a period of 20 days after wounding, in wounded rats and in controls, assays were conducted for: ascorbic acid in lens and liver, hydroxyproline, soluble protein, methionine and water in muscle and tendon, and free amino acids in muscle. 5. Relative to controls there was a decrease in lens and liver ascorbic acid, a rise in tendon hydroxyproline, a rise in muscle free amino acids, a fall in muscle protein and a rise in tendon and muscle water.
INTRODUCTION: Decreased serum albumin (SA) levels have been used extensively as prognostic indicators in many chronic debilitating diseases. The decrease may be partly compensated by globular proteins. The failure of globulins to compensate may reflect advanced disease. We examined the prognostic value of the level of serum globulins in colorectal and breast cancers.
METHODS: Data of 80 patients with advanced colon and breast cancers were analysed. Of these, 46 patients died within six months of measurement of their serum proteins, and the rest were followed-up for more than six months after measurements of their serum proteins were taken. A mathematical formula, representing the globulin compensation index (GCI), was recently developed from the measured SA levels and globulins. Patients were then classified into three categories: negative GCI and negative compensation; GCI of 0 to less than 1.0 with partial compensation; and GCI equal or greater than 1.0 with full compensation.
RESULTS: Among the deceased patients, 45.7 percent had negative GCI, compared to 26.5 percent of patients in the survivors group. For partial compensation, 30.4 percent of patients were from the deceased group, and 32.4 percent were from the survivors group. For full compensation (elevated GCI), 23.9 percent of patients were from the deceased group, compared to 41.1 percent from the survivors group (p-value equals 0.031).
CONCLUSION: Patients with low GCI are more likely to have bad prognoses, whereas those with higher GCI have more favourable prognoses. Globulin compensation may be a reliable prognostic factor in advanced colorectal and breast cancers, and possibly in other chronic illnesses. The GCI may serve as a useful tool in the measurement of this compensation.
Recently, the fruits of Hylocereus polyrhizus, known as red dragon fruit, have received much attention from growers worldwide. However, there is little toxicological information regarding the safety of repeated exposure to these fruits. The present study evaluated the potential toxicity of a methanol extract of H. polyrhizus fruit after acute and subchronic administration in rats. In the acute toxicity study, single doses of fruit extract (1250, 2500 and 5000 mg/kg) were administered to rats by oral gavage, and the rats were then monitored for 14 days. In the subchronic toxicity study, the fruit extract was administered orally to rats at doses of 1250, 2500 and 5000 mg/kg/day for 28 days. There was no mortality or signs of acute or subchronic toxicity. There was no significant difference in body weight, relative organ weight or hematological parameters in the subchronic toxicity study. Biochemical analysis showed some significant changes, including creatinine, globulin, total protein and urea levels. No abnormality of internal organs was observed between treatment and control groups. The lethal oral dose of the fruit extract is more than 5000 mg/kg and the no-observed-adverse-effect level (NOAEL) of the extract for both male and female rats is considered to be 5000 mg/kg per day for 28 days.
This report deals with an elderly lady with Guillain-Barre Syndrome (GBS), who presented with features of unusually severe hyponatraemia. The hyponatraemia was probably due to the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). The hyponatraemia resolved with water restriction and infusion of hypertonic saline; GBS was treated with human immunoglobulin (IVIG). This patient's experience stresses the importance of monitoring serum sodium levels as hyponatraemia has been identified to be a marker of poor prognosis in GBS.

A 35 kDa glycoprotein whose abundance was previously demonstrated to be enhanced in sera of patients with endometrial adenocarcinoma (n = 12), was isolated from pooled sera of three of the cancer patients using champedak galactose-binding lectin affinity chromatography in the present study. Subjecting it to 2-DE and MS/MS, the glycoprotein was identified as the O-glycosylated fragment of inter-alpha-trypsin inhibitor heavy chain H4 (ITIH4). When compared to control sera (n = 17), expression of the 35 kDa ITIH4 cleavage fragment was demonstrated to be significantly enhanced in sera of patients with breast carcinoma (n = 10), epithelial ovarian carcinoma (n = 10), and germ cell ovarian carcinoma (n = 10) but not in patients with nasopharyngeal carcinoma (n = 13) and osteosarcoma (n = 7). The lectin-based electrophoretic bioanalytical method adopted in the present study may be used to assess the physiological relevance of ITIH4 fragmentation and its correlation with different malignancies, their stages and progression.
