Introduction:
Previous studies have shown conflicting results on the efficacy of okra on lowering
blood sugar levels. This study aimed to determine the efficacy of okra in decreasing blood sugar
among patients with impaired fasting glucose.
Methods :
This was a randomized double-blind trial among patients with impaired fasting blood
glucose from three clinics in Antipolo City. Potential subjects were identified from records of the
three clinics, recruited and screened using the Finnish Diabetes Risk Score (FINDRISC) and fasting
blood sugar (FBS). Eligible patients were randomly assigned to receive okra or placebo capsules twice
daily for one month. The blood sugar after 30 days was compared with the baseline and the difference
between the okra and placebo groups was compared.
Results :
There was a significant difference between the pre-treatment and post-treatment FBS
levels, respectively, of both the okra and placebo groups (p-value <0.01). However, the difference
between the mean difference of the okra and placebo groups was not significant (p = 0.06).
Conclusion
The present study showed that okra capsules are not efficacious in lowering blood sugar
levels.

Okra (Abelmoschus esculentus (L.) Moench) has gained more popularity as an economically significant plant for its nutritional and medicinal value, especially in China. During 2014–2016, the root disease of okra was discovered in four okra commercial fields surveyed in China. A fungul was isolated from the infected tissues, and was identified by Verticillium dahliae based on morphological characteristics. Pathogenicity test demonstrated that the fungus was pathogenic on okra, and fulfilled Koch’s postulates. The analysis of three sequences revealed 99–100% identity with the reported V. dahliae strain in GenBank. Neighbor-joining analysis of the gene sequences revealed that the representative isolates were clustered with V. dahliae. To the best of our knowledge, this is the first report of Verticillium wilt of okra in China.

Foliar sprays of three plant resistance inducers, including chitosan (CH), potassium sorbate (PS) (C₆H₇kO₂), and potassium bicarbonates (PB) (KHCO₃), were used for resistance inducing against Erysiphe cichoracearum DC (powdery mildew) infecting okra plants. Experiments under green house and field conditions showed that, the powdery mildew disease severity was significantly reduced with all tested treatments of CH, PS, and PB in comparison with untreated control. CH at 0.5% and 0.75% (w/v) plus PS at 1.0% and 2.0% and/or PB at 2.0% or 3.0% recorded as the most effective treatments. Moreover, the highest values of vegetative studies and yield were observed with such treatments. CH and potassium salts treatments reflected many compounds of defense singles which leading to the activation power defense system in okra plant. The highest records of reduction in powdery mildew were accompanied with increasing in total phenolic, protein content and increased the activity of polyphenol oxidase, peroxidase, chitinase, and β-1,3-glucanase in okra plants. Meanwhile, single treatments of CH, PS, and PB at high concentration (0.75%, 2.0%, and/or 3.0%) caused considerable effects. Therefore, application of CH and potassium salts as natural and chemical inducers by foliar methods can be used to control of powdery mildew disease at early stages of growth and led to a maximum fruit yield in okra plants.

A severe damping-off disease of bush okra caused by Pythium aphanidermatum, was diagnosed in plastic houses in Der Attia village, 15 km southwest of El-Minia city, Egypt, during the winter of 2001. Bush okra seedlings showed low emergence with bare patches inside the plastic houses. Seedlings that escaped pre-emergence damping-off showed poor growth, stunting and eventually collapsed. Examination of the infected tissues confirmed only Pythium aphanidermatum, showing its typical intercalary antheridia, and lobulate zoosporangia. P. aphanidermatum was shown to be pathogenic on bush okra under pot and field experiments. Bacteria making inhibition zones against the damping-off fungus P. aphanidermatum were selected. Agar discs from rhizosphere soil of bush okra containing colonies were transferred onto agar plate culture of P. aphanidermatum. After 2 days of incubation, colonies producing clear zones of non-Pythium growth were readily detected. The two bacteria with the largest inhibition zones were identified as Pseudomonas fluorescens. Bush okra emergence(%) in both pot and plastic houses experiments indicated that disease control could be obtained by applying P. fluorescens to the soil or coating the bacteria to the bush okra seeds before sowing. In the plastic houses, application of the bacteria onto Pythium-infested soil and sowing bush okra seeds dressed with bacteria gave 100% emergence. In addition, This was the first reported disease of bush okra by this oomycete in Egypt.

Abelmoschus manihot (AM) is a medicinal plant rich in twenty kinds of separated active bio-components including flavones, polysaccharides, trannic acid, and long chain hydrocarbons. Among these, total flavones of A. manihot (TFA) are the major active component. In this review, the mechanisms of Huangkui capsule will be discussed as a preparation of AM to treat chronic kidney disease (CKD) by improving immunological reaction, inflammation, renal fibrosis, and renal tubular epithelial injury. Additionally, it has been reported that Huangkui capsule can ameliorate some clinical symptoms, proteinuria, hematuria, and renal function in patients with common CKD, such as nephrotic syndrome, diabetic nephropathy, Henoch-Schönlein purpura nephritis, IgA nephropathy, and membranous nephropathy.

Using soil chemical analysis method and combining with ICP-AES determination of mineral nutrition element content in rhizosphere soil of different planting age Abelmoschus Corolla Results show that along with the increase of planting age, the nitrogen (total N), available P and organic matter in rhizosphere soil of Abelmoschus Corolla content declined year by year and the soil got acidification. Heavy metal element content in agricultural land does not exceed national standards, but the content of element mercury (Hg) in rhizosphere soil of different planting age Abelmoschus Corolla declined. Request of microelement such as manganese (Mn) and zinc (Zn) had a increase tendency, but the content of magnesium (Mg) and sodium (Na) increased, and other nutrient elements had no changed rules or unchanged apparently. Consequently, exploring the change rules of different planting age Abelmoschus Corolla soil in rhizosphere as theoretical guidance of rational fertilization and subducting continuous cropping obstscles.

Renal tubular injury in patients with diabetic kidney disease(DKD) may be accompanied by glomerular and microvascular diseases. It plays a critical role in the progression of renal damage in DKD, and is now known as diabetic tubulopathy(DT). To explore the multi-targeted therapeutic effects and pharmacological mechanisms in vivo of total flavones of Abelmoschus manihot(TFA), an extract from traditional Chinese medicine for treating kidney disease, in attenuating DT, the authors randomly divided all rats into four groups: a normal control group(normal group), a DT model group(model group), a DT model+TFA-treated group(TFA group) and a DT model+rosiglitazone(ROS)-treated group(ROS group). The DT rat model was established based on the DKD rat model by means of integrated measures. After successful modeling, the rats in the four groups were continuously given double-distilled water, TFA suspension, and ROS suspension, respectively by gavage every day. After 6 weeks of treatment, all rats were sacrificed, and the samples of their urine, blood, and kidneys were collected. The effects of TFA and ROS on various indicators related to urine and blood biochemistry, renal tubular injury, renal tubular epithelial cell apoptosis and endoplasmic reticulum stress(ERS), as well as the activation of the protein kinase R-like endoplasmic reticulum kinase(PERK)-eukaryotic translation initiation factor 2α(eIF2α)-activating transcription factor 4(ATF4)-C/EBP homologous protein(CHOP) signaling pathway in the kidney of the DT model rats were investigated. The results indicated that hypertrophy of renal tubular epithelial cells, renal tubular hyperplasia and occlusion, as well as interstitial extracellular matrix and collagen deposition occurred in the DT model rats. Moreover, significant changes were found in the expression degree and the protein expression level of renal tubular injury markers. In addition, there was an abnormal increase in tubular urine proteins. After TFA or ROS treatment, urine protein, the characteristics of renal tubular injury, renal tubular epithelial cell apoptosis and ERS, as well as the activation of the PERK-eIF2α-ATF4-CHOP signaling pathway in the kidney of the DT model rats were improved to varying degrees. Therein, TFA was superior to ROS in affecting the pathological changes in renal tubule/interstitium. In short, with the DT model rats, this study demonstrated that TFA could attenuate DT by multiple targets through inhibiting renal tubular ERS-induced cell apoptosis in vivo, and its effect and mechanism were related to suppressing the activation of the PERK-eIF2α-ATF4-CHOP signaling pathway in the kidney. These findings provided preliminary pharmacological evidence for the application of TFA in the clinical treatment of DT.

Diabetes mellitus is a progressive metabolic disease and if left untreated, it is associated with failure of various organs. The search of safer antidiabetic agents leads to research of traditional medicinal plants.
OBJECTIVE: This study aimed to determine the effect of Abelmoschus esculentus water on the postprandial blood sugar among healthy normal human subjects.
METHOD: Randomized Open-Label Study. Normal healthy volunteers 20-60 years of age were recruited at Ospital ng Maynila Medical Center. After an overnight fast, FBS measurements were recorded. The were then randomized to Okra water and placebo. Both groups were also fed a standard meal in addition to the water of their respective groups. Capillary blood glucose was measured. after 2 hours and 4 hours. The difference in in the blood glucose of both groups was compared.
RESULTS: The mean random blood sugar of the subjects after intake of standard meal 2 hour postprandial in okra water group (109.92 ± 9.45 mg/dl) is greater than in the placebo group (108.35 ± 9.93 mg/dl), but not statistically significant (p>0.05). Also, the mean RBS 4 hours postprandial is less in okra water group than in placebo group (95.23 ± 6.99 versus 96.40 ± 9.13 mg/dl) but is also not statistically significant (p>0.05). Overall, the mean blood sugar of the okra water group from baseline to postprandial has no significant difference as compared to placebo.
CONCLUSION: Contrary to the previous animal studies, this present study, which used human subjects, showed no significant difference n the postprandial blood sugar level on subjects given with A. esculentus water as compared to placebo.
